Maybe "Suggested-by" would be more accurate, it is not like this feature
request was a bug report...

Should this not be guarded by `if (autostash)`?

Again, this should be guarded by `if (autostash)`, methinks.

Makes sense; this is now shared between the rebase and the merge modes.

Or shorter:

	argv_array_pushf(&args, "%s-autostash", opt_autostash ? "-" : "--no");

Ah, but that would mishandle `-1`. I bet I will be puzzled by this
again. Maybe it would make sense to mention in a code comment that it
can be `-1` in which case we leave it to `rebase` to use the config
settings to determine whether or not to autostash.
