tests: convert the 'file://\$TESTTMP' rule to an automatic substitution

The rule only triggered on non Windows platforms, even though Windows also
required an adjustment.  Automatic seems better.

The aggressive globbing in test-subrepo-svn.t was found and rewritten by the
substitution.

 """style and portability checker for Mercurial
 
 when a rule triggers wrong, do one of the following (prefer one from top):
  * do the work-around the rule suggests
  * doublecheck that it is a false match
  * improve the rule pattern
  * add an ignore pattern to the rule (3rd arg) which matches your good line
    (you can append a short comment and match this, like: #re-raises)
  * change the pattern to a warning and list the exception in test-check-code-hg
  * ONLY use no--check-code for skipping entire files from external sources

 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'
   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    *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.
