Subject: Show the current branch in the status view
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=f5a5e640f1fc42e3e95c51b827dff738e7dbf1ec;p=tig.git

Show the current branch in the status view

Also, improve the positioning of the cursor line after updates to
restore or select something that is "updateable". Adding new files
should now work more intuitively.
