Ignore work.conf (tmux configuration)
Add compressibility from garybernhardt/dotfiles

compressibility reports on how compressible a given file is using gzip
and bz2.

e.g.

    $ compressibility README.md
    file size 2095
    gzip size 934 (44%)
    bz2 size 1025 (48%)
FIXUP work.conf gitignore
Remove unused "pom" git alias

I'd never run "git push origin master", I might run "git push -u origin
master" the first time I'm setting up an origin remote but I usually
start from repos that already have a remote master branch already.
Add gbg alias to search git branches

Short for "git branch grep" even though we are using ack.
Add pu git aliases: git push -u

(git push -u automatically sets up the local branch to track the remote)
Add a guid method to irb: parse GUIDs from a given string
