Interactions in the working copy with the path some/file.c only make sense
if there is actually such a path in the working copy. If some/file.c is
deleted in r51, then either it isn't in your working copy (because you've
updated past r50) or it is, at r50 or earlier. If it is, you run 'svn cat
some/file.c' as usual. If it isn't, then the path 'some/file.c' has no
meaning anyway, so it falls to you to spelunk history and tell Subversion
more precisely what object you're talking about.
