[issue3165] diff on no-longer existing subrepository causes an error

[Rene Schipp von Branitz Nielsen]

New submission from Rene Schipp von Branitz Nielsen <rbn at vitesse.com>:

A while ago, we had a project with a number of subrepos. Recently, we've
removed one of them (in the transcript below, it's called main/my_subrepo).

Today I did a "hg diff -rA:B main/dir/some_file.txt", where A was from a
time where we had the subrepo and B is from the time where we didn't.
This gave the output below (anonymized):



$ hg diff -r16751:17347 main/dir/some_file.txt
diff -r 2555baeaacad -r bd54155d27e8 main/dir
some_file.txt
