When setting the upstream of the current branch to the 'main' branch
of the remote 'origin', i.e.,
$ git branch --set-upstream-to origin/main
it is easy to mistakenly write
$ git branch --set-upstream-to origin main
That is parsed as a request to set the upstream of the local branch
'main' to 'origin'. When 'main' does not exist, the command dies
with:
fatal: branch 'main' does not exist
pointing at a branch the user never meant to name.
When the operated-on branch is missing and '<remote>/<branch>' names
a real remote-tracking ref, suggest the intended form:
$ git branch --set-upstream-to=origin/main
The suggestion is gated on '<remote>/<branch>' existing so it only
appears when a slipped slash is the likely explanation.
