Want a feature to show me only files that are "perl"

[toddr]

I had to do this grep by hand because there was no other way to exclude all the noise from a straight grep.

I suggest a checkbox for show me only "perl" files.

Because the git grep is cached, you could use a feature like ack does to detect if the file is perl.

[atoomic]

currently using file extension is a workaround for it even if it do not show all 'perl' files and agree that a s special checkbox for this should be good to have
