Jean: could you show the actual "grep" command that you're using here, 
and the output of "grep --version"? That would help narrow down what's 
going on here.

M-x grep and friends should already be doing the right thing: when 
supported, it passes "--null" to "grep", which changes the output so 
that it separates the file name from the line number using a NUL 
character. The regexps in grep.el can then detect that output and parse 
it correctly.

I tried using a file name like the above, and it all works just fine for 
me. (I'm using GNU grep 3.4.)
