Speed up pre-commit by always passing at least one file to programs

Browse Source 
Some programs like the boilerplate or the flag checker will check the
whole repo if they aren't given a specific set of files to test. If you
use `git commit --amend` to change commit messages you will be calling
these functions with no args, and thus it take a lot longer to commit no
changes than it does to actually commit changes!
