checkout: inform the user when removing branch state
After a successful switch, if a merge, cherry-pick or revert is ongoing,
it is canceled. This behavior has been with us from the very early
beginning, soon after git-merge was created but never actually
documented [1]. It may be a good idea to be transparent and tell the
user if some operation is canceled.
I consider this a better way of telling the user than just adding a
sentence or two in git-checkout.txt, which will be mostly ignored
anyway.
PS. Originally I wanted to print more details like
warning: cancelling an in-progress merge from <SHA-1>
which may allow some level of undo if the user wants to. But that seems
a lot more work. Perhaps it can be improved later if people still want
that.
[1] ... and I will try not to argue whether it is a sensible behavior.
There is some more discussion here if people are interested:
