Hello,

Is there a way to specify revision ranges that has more power than
what's described in gitrevisions(7)?

For example, is there a way to show "the three most recent commits
preceding a tag that starts with "release-" that are also descendants of
commit aebecf."?

In Mercurial, this can be done with a more verbose syntax (e.g.
"last(ancestors(tag("re:release-.*")),3) and descendants(aebeccf)" for
the above example). Is there no equivalent in Git, or am I looking for
it in the wrong place?

Best,
-Nikolaus

This has no direct equivalent in Git. A lot can be done passing options
to "git rev-list" or so, for example, but I don't think a combination
can be found for your exact example.

The closest I get is:

  git log `git for-each-ref refs/tags/release- --format '%(refname)'` -3

Which lists 3 commits preceeding a tag whose name starts with release-.
