In preparation for `git-rebase--preserve-merges.sh` entering its after
life, we remove this (deprecated) option that would still rely on it.
To help users transition who still did not receive the memo about the
deprecation, we offer a helpful error message instead of throwing our
hands in the air and saying that we don't know that option, never heard
of it.

When 46af44b07d (pull --rebase=<type>: allow single-letter abbreviations
for the type, 2018-08-04) landed in Git, it had the side effect that
not only 'pull --rebase=<type>' accepted the single-letter abbreviations
but also the 'pull.rebase' and 'branch.<name>.rebase' configurations.
However, 'git remote rename' did not honor these single-letter
abbreviations when reading the 'branch.*.rebase' configurations.
We now document the single-letter abbreviations and both code places
share a common function to parse the values of 'git pull --rebase=*',
'pull.rebase', and 'branches.*.rebase'.
The only functional change is the handling of the `branch_info::rebase`
value. Before it was an unsigned enum, thus the truth value could be
checked with `branch_info::rebase != 0`. But `enum rebase_type` is
signed, thus the truth value must now be checked with
`branch_info::rebase >= REBASE_TRUE`
