Subject: [PATCH 01/11] builtin rebase: support --onto
Date: Wed, 8 Aug 2018 19:33:20 +0545 [thread overview]
Message-ID: <20180808134830.19949-2-predatoramigo@gmail.com> (raw)
In-Reply-To: <20180808134830.19949-1-predatoramigo@gmail.com>
The `--onto` option is important, as it allows to rebase a range of
commits onto a different base commit (which gave the command its odd
name: "rebase").
This commit introduces options parsing so that different options can
be added in future commits.
Note: As this commit introduces to the parse_options() call (which
"eats" argv[0]), the argc is now expected to be lower by one after this
patch, compared to before this patch: argv[0] no longer refers to the
command name, but to the first (non-option) command-line parameter.
