git: note install locations in caveats
ENV: Use /usr/X11 instead of symlink
Edit keg-only message
Changed X11R6 paths to X11

Fixed formulas referencing X11 via the X11R6 symlink to instead reference the
path X11 should be at directly (in case the user doesn't have that symlink,
like I didn't)

Fixed reading branch name

The git command now uses --git-dir instead of --work-tree.
Using --work-tree won't work if you are inside another Git repository.
