Dependency parser treats valid filename characters as line-breaks

[MarcKamradt]

I have some .dep files generated by custom tools that include filenames containing characters such as & or ' (don't ask why. musicians and visual artists get creative there, too).

These are valid filename characters but seem to be treated as line-breaks instead. I was able to resolve this issue by hacking the table in depfile_parser.cc to include those characters.

I'm experiencing the same type of issues with additional characters, e.g., ' or [ as well as &. Is there a reason for triggering line-breaks for any printable characters apart from spaces and semicolons which are needed in the deps file? Looking at, for instance, clang we only escape spaces, # and $, which triggeres errors for paths containing strange characters.
