AucTeX / Emacs syntax highlighting problem

[Jörg Johannes <liste_joerg@gmx.de>]

Hello List

I have a file called header.tex in my home directory which I use for 
every LaTeX document. When I try to do
\input{$HOME/header}
at the very beginning of my document, emacs colors everything in 
math-mode-colour because of the "$"-sign. I do not want to use the 
absolute path, because I use the same tex-files on my home box ($HOME == 
/home/jorg) and on an IRIX box at university ($HOME == 
/usr/people/jorg). Can I tell emacs to ignore the "$" sign in \input{} 
context? (is this a bug?). To work around this, I \input another file 
called $HOME/newcommands, so the math mode stops there... but this is 
not very beautiful.

Thanks
joerg
