Update of /cvsroot/vim-latex/vimfiles/ftplugin/latex-suite
In directory sc8-pr-cvs1:/tmp/cvs-serv31508
Modified Files:
main.vim
Log Message:
Change: Initially, Tex_EscapeForGrep would always double backslashes at
least once to account for the fact that the user means the external
grep command to see the string ``\\label`` when he passes
``\label`` to this function. But making such guesses is bad for
cases when we want to pass a single ``\`` to the external grep
command (for instance when we want to pass ``\<word\>`` to the
external grep command). Therefore, stop this function from making
any guesses about what the user might have wanted the external
command to see. This function now expects the user to pass the
exact string which he wants the external grep command to see.
