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]       $SVNREPOURL/externals" >> .hgsub
  $ svn co -r5 --quiet "$SVNREPOURL"/externals obstruct
  $ hg commit -m 'Start making obstructed working copy'
  $ hg book other
  $ hg co -r 'p1(tip)'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (leaving bookmark other)
  $ echo "obstruct =        [svn]       $SVNREPOURL/src" >> .hgsub
  $ svn co -r5 --quiet "$SVNREPOURL"/src obstruct
  $ hg commit -m 'Other branch which will be obstructed'

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    *obstruct/other (glob)
  Checked out revision 1.
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (activating bookmark other)

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

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