From a330de31d18ca08c773c64e3657b3bafd59cf751 Mon Sep 17 00:00:00 2001 From: Vicent Marti Date: Thu, 24 Oct 2013 14:01:41 -0400 Subject: revision: allow setting custom limiter function This commit enables users of `struct rev_info` to peform custom limiting during a revision walk (i.e. `get_revision`). If the field `include_check` has been set to a callback, this callback will be issued once for each commit before it is added to the "pending" list of the revwalk. If the include check returns 0, the commit will be marked as added but won't be pushed to the pending list, effectively limiting the walk.
