I almost proposed this, but the syntax would not be this one. Indeed,
if I understand correctly, ._at_50 means the URL of the current directory
at revision 50, while I want the current directory at revision 50,
taking into account the possible renamings (i.e. not a peg-rev on ".",
but -r50 on "."). Now, one could imagine a slightly different syntax,
e.g.

  svn cat .@:50/some/file.c

where ":" means that one follows the history (like with -r).

Actually, I don't think that peg revisions (i.e. without following the
history) make much sense on objects relative to the current directory
(unless its URL has not changed since the peg-rev).

Yes.
