Which is exactly what my git-hist does:

What do I miss here?

fatal: cannot describe 'c2220c8a544af5cd5419e238eb5f43b1f079ad85'

My git-hist is just a perl script that collects the combined
information of

	git-log --pretty=format:'%h %ct %s'
	git-show-ref --tags
and	git-blame file

I could also make it a reformatting wrapper over several calls to

	git blame -l file | git name-rev --stdin --tags

Which is probably faster for a single file, but slower on multiple files
