copies: clean up _related logic
The limit parameter was never actually used, since the only way the 4th case
could be reached was if f1r and f2r converged. The new code makes this clear,
and additionally reduces the conditional block to just 3 cases.
# Read the output of a "svn log --xml" command on stdin, parse it and
# print a subset of attributes common to all svn versions tested by
# hg.
