When performing a rebase with --rebase-merges using either a custom
strategy specified with -s or an octopus merge, and at the same time
having gpgsign enabled (either rebase -S or config commit.gpgsign), the
operation would fail on making the merge commit. Instead of "-S%s" with
the key id substituted, only the bare key id would get passed to the
underlying merge command, which tried to interpret it as a ref.

Fix the issue and add test cases as suggested by Johannes Schindelin.

Good.  And later you'd add "else" to explicitly turn it off, I presume?

Insert

	test_unconfig commit.gpgsign &&

here.  That would make it explicit that we are checking the base
case where only the command line option is given.

Use "git config" for consistency.

We'd want another one, which is to give --gpg-sign from the command
line when this is in effect:

	git config commit.gpgsign false

i.e. not "test_unconfig" that removes the configuration, but
explicitly configured not to sign

Thanks.
