[PATCH 0/3] rev-list: allow missing tips with --missing

[Christian Couder <christian.couder@gmail.com>]

A recent patch series, kn/rev-list-missing-fix [1] extended the
`--missing` option in git-rev-list(1) to support commit objects.

Unfortunately, git-rev-list(1) with `--missing` set to something other
than 'error' still fails, usually with a "fatal: bad object <oid>"
error message, when a missing object is passed as an argument.

This patch series removes this limitation and when using
`--missing=print` allows all missing objects to be printed including
those that are passed as arguments.

Patches 1/3 (revision: clarify a 'return NULL' in get_reference()) and
2/3 (t6022: fix 'even though' typo in comment) are very small
preparatory cleanups.

Patch 3/3 (rev-list: add --allow-missing-tips to be used with
--missing=...) introduces the new `--allow-missing-tips` option that
allows git-rev-list(1) with `--missing` to not fail when one of the
tips it is passed is missing.
