When I use environment variables (such as $HOME) in a .tex file, the $
triggers math mode syntax highlighting. The result is that the rest
of the buffer, until the next $, is highlighted as if it were in math
mode. Some examples:
\includegraphics{$HOME/path/to/graphic}
\bibliography{$HOME/path/to/bib1,$HOME/path/to/bib2}
I currently use the following hack to get around this behavior:
\bibliography{%
$HOME/path/to/bib1,%$
$HOME/path/to/bib2,%$
}
where the second $ on each line "closes" the math mode for
syntax-highlighting purposes, so at least the rest of the buffer is not
affected.
