SVN wants all paths to start with a slash. Unfortunately, Windows ones
don't. Handle that.

Test case where subversion would fail to update the subrepo because there
are unknown directories being replaced by tracked ones (happens with rebase).

Modify one of the externals to point to a different path so we can
test having obstructions when switching branches on checkout:
  $ hg checkout tip
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo "obstruct =        [svn]       $SVNREPO/externals" >> .hgsub
  $ svn co -r5 --quiet "$SVNREPO"/externals obstruct
  $ hg commit -m 'Start making obstructed wc'
  committing subrepository obstruct
  $ hg book other
  $ hg co -r 'p1(tip)'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo "obstruct =        [svn]       $SVNREPO/src" >> .hgsub
  $ svn co -r5 --quiet "$SVNREPO"/src obstruct
  $ hg commit -m 'Other branch which will be obstructed'
  committing subrepository obstruct
  created new head

Switching back to the head where we have another path mapped to the
same subrepo should work if the subrepo is clean.
  $ hg co other
  A    $TESTTMP/rebaserepo/obstruct/other
  Checked out revision 1.
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

This is surprising, but is also correct based on the current code:
  $ echo "updating should (maybe) fail" > obstruct/other
  $ hg co tip
  abort: crosses branches (merge branches or use --clean to discard changes)
  [255]

Point to a Subversion branch which has since been deleted and recreated
First, create that condition in the repository.
