I am trying to get a lint, commit message spell checker, trailing
whitespace check in code etc work on my *local machine* before
committing. pre-receive works in the server right? Its also time I
need to seriously consider a pre-commit hook to "Reject commits made
between 4am and 7am with a note to go to bed."

Its ok since I am the only one to use it because I want to make my
commits cleaner and better.  There is always --no-verify for skipping
hooks.

Isn't `git commit $@ --dry-run --porcelain` better for parsing or am I
missing something ?
