When the source file is empty, the calculation of the merge score
results in a division by zero. In the situation:
== preimage == == postimage ==
F (empty file) F (a large file)
E (a new empty file)
it does not make sense to consider F->E as a rename, so it is better not
to break the pre- and post-image of F.
Bail out early in this case to avoid hitting the divide-by-zero. This
causes the merge score to be left at zero.

There was no good way to ask "I have a random string that came from

"help -a" (help all) gives the list of available commands and then
further gives hints on the use of "git help". Separate these into
two steps, because we will add "help -g" (help guides) that want to
also show the overall hints after it is done.
While at it, change the definition of the "-a" option to use OPT_BOOL,
not the deprecated OPT_BOOLEAN. We do not behave differently when
the user gives the "-a" option multiple times, e.g. "git help -a -a".

If the user requests to --set-upstream-to a branch that does
not exist, then either:
1. It was a typo.
2. They thought the branch should exist.
In case (1), there is not much we can do beyond showing the
name we tried to use. For case (2), though, we can help to
guide them through common workflows.

If we refuse a branch operation because the tracking
start_name the user gave us is bogus, we just print
something like:
fatal: Cannot setup tracking information; start point is not a branch
If we mention the actual name we tried to use, that may help
the user figure out why it didn't work (e.g., if they gave
us the arguments in the wrong order).

If we are trying to set the upstream config for a branch,
the create_branch function will check both that the name
resolves as a ref, and that it is either a local or
remote-tracking branch.
However, before we do so we run get_sha1 on it to find out
whether it resolves at all (since the create_branch function
is also used to create actual branches, it wants to know
where to start the new branch). This means that if you feed
a ref that does not exist to "branch --set-upstream-to",
rather than getting a helpful message about tracking, you
only get "not a valid object name".

These tests pass with the current code, but let's make sure
we don't accidentally break the behavior in the future.
Note that our tests expect failure when we try to set the
upstream to or from a missing branch. Technically we are
just munging config here, so we do not need the refs to
exist. But seeing that they do exist is a good check that
the user has not made a typo.
