Yeah, '$' lowers the chances of wrapping but in corner cases, it'll be
just as bad.
Junio's suggestion is one way to go. Another is Marc's idea of
breaking lines, so we could in theory have something like this
From ...
* [new branch] branch1 -> origin/$
* [new branch] branch2 -> origin/$
* [new branch] some-really-long-branch-name
-> origin/$
+ 1234abc..5678def branch3 -> origin/$ (forced update)
* [new branch] branch4 -> origin/$
Or, for a very long branch name, we could put replace a big chunk of
it with an ellipsis. If it's long enough, I guess you can still figure
the branch name with a big gap in the middle (or left or right).
From ...
* [new branch] branch1 -> origin/$
* [new branch] branch2 -> origin/$
* [new branch] some-re...anch-name -> origin/$
+ 1234abc..5678def branch3 -> origin/$ (forced update)
* [new branch] branch4 -> origin/$
And with that we get dangerously close to full customization using
pretty placeholders :)
