`grep -o` not available in git bash for Windows

[bryanburgers]

The grep in git bash for Windows does not support the -o option. grep -o plays a pretty big part in the (staged|conflicted|unstaged|untracked)_status, which means that, on Windows, using git-radar results in the following message repeated about 20 times.

grep: invalid option -- o
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.

looks like these guys had a similar problem here. That link will take you to a comment that says that possibly upgrading grep to a newer version may solve the problem...

Alternatively, it is possible that maybe we can use sed instead, assuming that git bash has support for sed.

Alternatively (again) I have also found this gist which appears to be a bash script that will upgrade your grep on git bash for you.

It looks like it assumes you have 7-zip though, so if you don't have that you will probably have to install it in order to use this.
