Thanks to the option parapparatus, the text of a footnote with the "normal" arrangement is allowed to contain paragraph breaks, like this:
\edtext{Lemma}{%
\Afootnote{First paragraph.
\par % paragraph break
Second paragraph.}}
However, I get an error message whenever the footnote in question is nested within (the \edtext of) another footnote:
\edtext{Lemma Bigger FN...
%
\edtext{Lemma Nested FN.}{%
\Afootnote{First paragraph.
\par % paragraph break
Second paragraph.}}
%
...end of lemma.}{%
\Afootnote{Text Bigger FN.}}
The error message is:
Runaway argument?
{Lemma Bigger FN... \edtext {Lemma Nested FN.}{\Afootnote {First para\ETC.
./MWE_parbreak_in_footnote.tex:19: Paragraph ended before \showlemma was complete.
<to be read again>
\par
l.17 \Afootnote{Text Bigger FN.}}
This is the classic error that stems from inserting a paragraph break into a macro that is non-\long.
AFAICS, parapparatus redefines \Xfootnote{} to be \long, i.e., it can contain paragraph breaks.
But this mechanism doesn't work if it is nested within another footnote. (Regardless of the arrangement of the "bigger" footnote, be it "normal" or "paragraph"...)
Is this intended? The manual doesn't mention it (§6.2.4). Or is it a bug resulting from the interaction of \edtext (non-\long) with the \long argument of \Xfootnote?
Or am I doing something wrong?
Here's a MWE:
\documentclass{article}
\usepackage[series={A,B},noend,nofamiliar,noeledsec,parapparatus]{reledmac}
\Xnotefontsize[A]{\normalsize}
\begin{document}
\beginnumbering
\pstart
\edtext{Lemma Bigger FN...
%
\edtext{Lemma Nested FN.}{%
\Afootnote{First paragraph.
\par % paragraph break
Second paragraph.}}
%
...end of lemma.}{%
\Afootnote{Text Bigger FN.}}
\pend
\endnumbering
\end{document}
(FWIW: We use \Afootnotes to render the author's own marginal notes on his text. When we need to comment on these notes, since reledmac cannot append a critical footnote to a footnote, we need to "simulate" our usual critical apparatus of \Bfootnotes. That is, we print our commentary within the foonote text, in a new paragraph, in a smaller font.
Anyway, this can also be obtained without using parapparatus and a par-break, f.i. a simple \newline will do.)
