Since 610e2b9240
(blame: validate and peel the object names on the
ignore list, 2020-09-24) git blame reports checks if objects specified
with --ignore-rev and in files loaded with --ignore-revs-file and config
option blame.ignoreRevsFile are actual objects and dies if they aren't.
The intent is to report typos to the user.
This also breaks the ability to use a single ignore file for multiple
repositories. Typos are presumably less likely in files than on the
command line, so alerting is less useful here. Restore that feature by
skipping non-commits without dying.
