Subject: vcsh: Make status show commits ahead/behind remote
X-Git-Url: https://git.madduck.net/code/vcsh.git/commitdiff_plain/6046fecd2148d7ab42e9c68bcc8ce04d74fe10cd?ds=sidebyside;hp=-c

vcsh: Make status show commits ahead/behind remote

This is work in progress:
* It does not deal with repos without a remote tracking branch
* It does not share any info if run on a single repo
* I should probably factor this out in a new function

github: in response to richih/vcsh#123
