Below are two schemes I did with xyling (which I understand builds on xypic, hence the tag); they are identical except for the labelling and one arrow being dashed in the lower one. They are also identical in width.

Now if I move the comment in line 6 to line 7 (so that line 7 then reads \fbox{%GB-Theory), then this fbox's width will be slightly reduced. Same thing goes for the comment in line 14 and fbox{ in line 15. I put the comment right after { and the width will be slightly reduced. I have no idea why.

\documentclass{article}
\usepackage{xyling}
\date{}
\begin{document}

%GB-Theory
\fbox{
\Treek[.5]{3}{
       & \K{D-Structure}\AR{d} \\
       & \K{S-Structure} \AR{dl}\AR{dr}\\
\K{LF} & & \K{PF} }
}

%Minimalism
\fbox{
\Treek[.5]{3}{
       & \K{\textsc{numeration}}\AR{d} \\
       & \K{\textsc{spellout}} \AR{dl}\ARdash{dr}\\
\K{LF} & & \K{PF} }
}
\end{document}

A newline is a space. If you comment it out, you remove the space from the list of tokens TeX parses.
