Remove period from biblatex entry when there is no editor

Question

Following suggestions by @moewe in the questions Enable "firstinits" in biblatex only for editors and Move names of editors followed by (Ed./Eds.) and a comma before title in biblatex, I have the code you see below. The problem here is that it prints a superfluous period after In when the collection has no editor, as seen in the Brekke entry.

\documentclass{article}
\usepackage[style = authoryear-comp]{biblatex}

\renewcommand*{\intitlepunct}{\space} % remove colon after "In:" for articles in books

%% Abbreviate first names of editors
\DeclareNameAlias{byeditor}{first-last-inits}
\DeclareNameFormat{first-last-inits}{%
  \usebibmacro{name:first-last}{#1}{#4}{#5}{#7}%
  \usebibmacro{name:andothers}}
%%

%% Move names of editors before the book title, and add "(Eds.)"
\usepackage{xpatch}
\DeclareNameAlias{editorin}{first-last-inits}
\newbibmacro*{byeditor:in}{%
  \ifnameundef{editor}
    {}
    {\printnames[editorin]{editor}%
     \addspace\bibsentence%
     \mkbibparens{\usebibmacro{editorstrg}}%
     \clearname{editor}%
     \printunit{\addcomma\space}}}
\xpatchbibdriver{incollection}
  {\usebibmacro{in:}%
   \usebibmacro{maintitle+booktitle}%
   \newunit\newblock
   \usebibmacro{byeditor+others}}
  {\usebibmacro{in:}%
   \usebibmacro{byeditor:in}%
   \setunit{\labelnamepunct}\newblock
   \usebibmacro{maintitle+booktitle}%
   \newunit\newblock
   \usebibmacro{byeditor}}
  {}{}
%%

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@INCOLLECTION{brekke1881,
    AUTHOR = "K. Brekke",
    BOOKTITLE = "Indbydelsesskrift til den offentlige examen i juni og juli 1881 ved Aars og Voss's latin- og realskole",
    TITLE = "Bidrag til dansk-norskens lydl{\ae}re",
    YEAR = "1881",
    LOCATION = "Kristiania",
    PAGES = "1--66",
    PUBLISHER = "W. C. Fabritius"}

Another option is to follow the suggestion by @Guido (also to my question Move names of editors followed by (Ed./Eds.) and a comma before title in biblatex), and use the code below. The problem here is that the first names of the editors are not abbreviated (naturally enough, since I didn't ask for it in connection with that question).

\documentclass{article}
\usepackage[style = authoryear-comp]{biblatex}

\renewcommand*{\intitlepunct}{\space} % remove colon after "In:" for articles in books

%% Move names of editors before the book title, and add "(Eds.)"
\usepackage{xpatch}
\xpatchbibmacro{editorstrg}{\bibstring}{\bibcpstring}{}{}

\renewbibmacro*{in:}{
  \ifentrytype{incollection}{%
  \DeclareNameAlias{editor}{first-last}
  \printtext{In}
  \ifnameundef{editor}
    {}
    {\printnames{editor}%
     \addspace 
     \mkbibparens{\usebibmacro{editorstrg}}
     \setunit{\addcomma\addspace}% 
    }%
  \printfield[book]{booktitle}
  \clearfield{booktitle}
  \clearname{editor}
  }
  {}%
}%%

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@INCOLLECTION{brekke1881,
    AUTHOR = "K. Brekke",
    BOOKTITLE = "Indbydelsesskrift til den offentlige examen i juni og juli 1881 ved Aars og Voss's latin- og realskole",
    TITLE = "Bidrag til dansk-norskens lydl{\ae}re",
    YEAR = "1881",
    LOCATION = "Kristiania",
    PAGES = "1--66",
    PUBLISHER = "W. C. Fabritius"}
@INCOLLECTION{jahr2007,
    AUTHOR = "Ernst H{\aa}kon Jahr",
    BOOKTITLE = "{\AA} sj{\aa} samfunnet gjennom spr{\aa}ket",
    EDITOR = "Gunnstein Akselberg and Johan Myking",
    TITLE = "Bruk av omgrepa 'standardtalem{\aa}l', 'normalisering' og 'knot' for {\aa} skildre spr{\aa}ktilh{\o}va i Noreg i dag",
    YEAR = "2007",
    LOCATION = "Oslo",

So my question is: How can I modify the suggestion by @moewe to get rid of the unwanted period in case of missing editors, or how can I modify the suggestion by @Guido to abbreviate the first names of editors?

If you want to continue using my modifications, the problem you're facing seems to be at first glance of the same kind like When author field is empty, do not put colon after prenote in authortitle-comp. I'm guessing a \printunit for \intitlepunct in the in: bibmacro might help: \renewbibmacro*{in:}{\printtext{\bibstring{in}}\printunit{\intitlepunct}}. (I will investigate this properly tomorrow though.) — moewe, Sep 02 '14 at 21:36
If you prefer to use Guido's solution, changing the line \DeclareNameAlias{editor}{first-last} to \DeclareNameAlias{editor}{first-last-inits} and copying \DeclareNameFormat{first-last-inits}{\usebibmacro{name:first-last}{#1}{#4}{#5}{#7}\usebibmacro{name:andothers}} to that document should help (untested, but I should think it does the job). That is, you should be able to apply the answer to Enable “firstinits” in biblatex only for editors here as well, but the name format in question is editor, not byeditor (so we have to change that). — moewe, Sep 02 '14 at 21:43
@moewe I followed your suggestion for modifying the suggestion by @Guido. It works, but now I notice that his code prints (ed.), with a lowercase e instead of (Ed.), when there is only one editor. I've put a comment about that to his answer. — Sverre, Sep 03 '14 at 11:30
@moewe I've also noticed that @Guido's code inappropriately prints the title of the volume directly after (Eds.),, where rather the main title should be. I'll await the fix for your own code, then :). — Sverre, Sep 03 '14 at 11:59
It seems my first guess about what to do to fix my modification was not at all far off, see my answer below. — moewe, Sep 03 '14 at 14:18

To fix my code, you can modify the in: bibmacro to

\renewbibmacro*{in:}{%
  \printtext{\bibstring{in}}%
  \printunit{\intitlepunct}}

that is, we use \printunit (a explanation as to why we need to use \printunit can be found in this answer of mine).

If you are using \renewbibmacro{in:}{\ifentrytype{article}{}{\printtext{\bibstring{in}\intitlepunct}}} (as you do here), the fix would obviously be \renewbibmacro{in:}{\ifentrytype{article}{}{\printtext{\bibstring{in}}\printunit{\intitlepunct}}}. — moewe, Sep 03 '14 at 14:21
