[BUG] DOS filetype and pre_commit hook

[MALET Jean-Luc <jeanluc.malet@xxxxxxxxx>]

I use git for tracking change on the project I'm working on and the 
sourcecode is in dos text encoding (<CR><LF>)
when I commit I have to use the --no-verify option because the perl part 
of the hook (btw isn't it possible to have git not depend on perl?) 
don't use the right regexp to track if there is trailing whitespace
the corresponding regex to be used with grep is :
grep -E '^\+.*[[:blank:]]+[[:space:]]$'

because <CR> is matched by [[:space:]] and then a line like :

no trailing whitespace<CR><LF>

will trigger a trailing whitespace event

See the attached file that correct the issue

Best Regards,
JLM
