The %prog command shows differences between project revisions of manifest1 and

instead. Both absolute and relative paths may be used for manifests. Relative

paths start from project's ".repo/manifests" folder.

Only changed projects may contain commits, and commit status always starts with

Unreachable revisions may occur if project is not up to date or if repo has not

synced and their revisions won't be found.
