Subject: rev-list: refactor early option parsing
X-Git-Tag: v2.50.0-rc0~107^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c9907a19169c186da444e22991df7c9f4237ac40;p=thirdparty%2Fgit.git

rev-list: refactor early option parsing

Before invoking `setup_revisions()`, the `--missing` and
`--exclude-promisor-objects` options are parsed early. In a subsequent
commit, another option is added that must be parsed early.

Refactor the code to parse both options in a single early pass.
