Special pattern for filename/basename?

[mitchellwrosen]

Right now \0 refers to the entire match of the regex, which is not necessarily the entire file.

It might be nice to launch sos like so:

sos -p 'hs$' -c 'stack ghc <the-file>'

and have it run stack ghc on any modified file that ends in hs. However, I believe the simplest way to do this (currently) is:

sos -p '.*hs$' -c 'stack ghc \0'

Not too bad, but that extra .* can be annoying. Would it make sense to have magic variable names for the absolute path matched and/or the basename matched?
