 debugignore with no hgignore should be deterministic:

 Issue562: .hgignore requires newline at end:
 
   $ touch foo

   $ touch baz
   $ cat > makeignore.py <<EOF
   > f = open(".hgignore", "w")

 Check patterns that match only the directory
 
 "(fsmonitor !)" below assumes that fsmonitor is enabled with
 "walk_on_invalidate = false" (default), which doesn't involve
 re-walking whole repository at detection of .hgignore change.
 
   $ echo "^dir\$" > .hgignore
   $ hg status
   A dir/b.o
   ? .hgignore
   ? a.c
   ? a.o
   ? dir/c.o (fsmonitor !)
   ? syntax
 
 Check recursive glob pattern matches no directories (dir/**/c.o matches dir/c.o)
 
   $ echo "syntax: glob" > .hgignore
   $ echo "dir/**/c.o" >> .hgignore
   $ touch dir/c.o
   $ mkdir dir/subdir
   $ touch dir/subdir/c.o
   $ hg status
   A dir/b.o
   ? .hgignore
   ? a.c
   ? a.o
   ? syntax
   $ hg debugignore a.c
   a.c is not ignored
   $ hg debugignore dir/c.o
   dir/c.o is ignored
   (ignore rule in $TESTTMP/ignorerepo/.hgignore, line 2: 'dir/**/c.o') (glob)
 
 Check rooted globs
 
   $ hg purge --all --config extensions.purge=
   $ echo "syntax: rootglob" > .hgignore
   $ echo "a/*.ext" >> .hgignore
   $ for p in a b/a aa; do mkdir -p $p; touch $p/b.ext; done
   $ hg status -A 'set:**.ext'
   ? aa/b.ext
   ? b/a/b.ext

 Check using 'include:' in ignore file

   $ hg status
   skipping unreadable pattern file 'badignore': $ENOENT$
   A dir/b.o

 Check using 'include:' while in a non-root directory
 
   $ cd ..
   $ hg -R ignorerepo status
   A dir/b.o
   $ cd ignorerepo
 
 Check including subincludes
 
   $ hg revert -q --all
   $ hg purge --all --config extensions.purge=
   $ echo ".hgignore" > .hgignore
   $ mkdir dir1 dir2
   $ touch dir1/file1 dir1/file2 dir2/file1 dir2/file2
   $ echo "subinclude:dir2/.hgignore" >> .hgignore
   $ echo "glob:file*2" > dir2/.hgignore
   $ hg status
   ? dir1/file1
   ? dir1/file2
   ? dir2/file1
 
 Check including subincludes with other patterns
 
   $ echo "subinclude:dir1/.hgignore" >> .hgignore
 
   $ mkdir dir1/subdir
   $ touch dir1/subdir/file1
   $ echo "rootglob:f?le1" > dir1/.hgignore

   $ echo "regexp:f.le1" > dir1/.hgignore
   $ hg status
   ? dir1/file2

 Check multiple levels of sub-ignores
 
   $ touch dir1/subdir/subfile1 dir1/subdir/subfile3 dir1/subdir/subfile4
   $ echo "subinclude:subdir/.hgignore" >> dir1/.hgignore
   $ echo "glob:subfil*3" >> dir1/subdir/.hgignore
 
   $ hg status
   ? dir1/file2
   ? dir1/subdir/subfile4
   ? dir2/file1
 
 Check include subignore at the same level
 
   $ mv dir1/subdir/.hgignore dir1/.hgignoretwo
   $ echo "regexp:f.le1" > dir1/.hgignore
   $ echo "subinclude:.hgignoretwo" >> dir1/.hgignore
   $ echo "glob:file*2" > dir1/.hgignoretwo
 
   $ hg status | grep file2
