[PATCH] Issue #3126 - svn mergeinfo should consider non-inheritable ranges as merged

Right now the svn mergeinfo subcommand doesn't consider
non-inheritable ranges as merged, see
http://subversion.tigris.org/issues/show_bug.cgi?id=3126#desc5.

Quick example, if a path has this mergeinfo:

>svn pg svn:mergeinfo -vR A_COPY
  Properties on 'A_COPY':
    svn:mergeinfo
      /A:4,6*

svn mergeinfo considers r6 as eligible:

>svn mergeinfo --show-revs eligible %url%/A A_COPY
  r3
  r5
  r6

Nor does it consider it merged:

>svn mergeinfo --show-revs merged %url%/A A_COPY
  r4

This seems completely wrong, r6 *has* been merged to A_COPY, just not
any deeper, so r6 should show as merged.

Keep in mind that the mergeinfo subcommand as it stands today tells us
what has/hasn't been merged to a path, but doesn't consider differing
mergeinfo under that path. Since non-inheritable mergeinfo is about
what is under a path it shouldn't matter either.

The attached patch corrects this and adds a test. Does anyone
disagree with this change?
