If repo has detached HEAD ges throws an error

[espoelstra]

fatal: HEAD does not point to a branch
/home/espoelstra/projects/foss/git-extra-status/bin/git-status: 13: [: =: argument expected
/home/espoelstra/projects/foss/git-extra-status/bin/git-status: 15: [: =: argument expected
 [jenkins_wrapper] - HEAD
    ▲ Push Needed``` 

This is easy to replicate in any repository by running `git checkout HEAD~` then running `ges`.

Hi @espoelstra,

Thanks for reporting. Do you have any fix for this? Please feel free to send a pull request.

The easiest way to fix the shell script errors is changing things like:

if [ $LOCAL = $REMOTE ]; then

to

if [ "${LOCAL}" = "${REMOTE}" ]; then

But that still doesn't resolve the fatal: HEAD does not point to a branch.

I found something on stack overflow that seems to do the trick for detecting a detached HEAD state.
