Fix a memory leak in code added in5d7eeee2ac
(git-show: grok blobs, trees and tags, too, 2006-12-14). As we iterate over a "<revision>..." command-line and encounter ad OBJ_COMMIT we want to use our "struct rev_info", but with a "pending" array of one element: the one commit we're showing in the loop. To do this5d7eeee2ac
saved away a pointer to rev.pending.objects and rev.pending.nr for its iteration. We'd then clobber those (and alloc) when we needed to show an OBJ_COMMIT. We'd therefore leak the "rev.pending" we started out with, and only free the new "rev.pending" in the "OBJ_COMMIT" case arm as prepare_revision_walk() would draw it down. Let's fix this memory leak. Now when we encounter an OBJ_COMMIT we save away the "rev.pending" before clearing it. We then add a single commit to it, which our indirect invocation of prepare_revision_walk() will remove. After that we restore the "rev.pending". Our "rev.pending" will then get free'd by the release_revisions() added inf6bfea0ad0
