That's important usability difference, IMO.

I believe in SVN, you only need to bother with peg revision in order to identify the object you want to work with, in case it
does not exist in current place, or it was a different object with the same name in past. In other cases, SVN will walk the history
just fine. E.g. I just run this in SVN:
~/Sources/boost-trunk/tools/build/v2/engine$ svn diff -c18888 jam.c
and got a diff. This is an old revision, the 'engine' directory did not exist back then, and until revision 64010, and the file itself
was moved twice. So, moving files is in fact easier in SVN. (I vaguely believe that in early SVN versions, the above command would
have required peg revision, but it's was long time ago).
