match: drop unnecessary adding of '' to set of dirs

This breaks some tests for "rootfilesin:" in a pattern matcher even
more, but that just shows how broken that case is.

Generate some content.  The sed filter drop CR on Windows, which is dropped in

Make a clean directory for future tests to build off of

Split a head

  $ hg split 'all()'
  abort: cannot split multiple revisions

This function splits a bit strangely primarily to avoid changing the behavior of
the test after a bug was fixed with how split/commit --interactive handled
`commands.commit.interactive.unified=0`: when there were no context lines,
it kept only the last diff hunk. When running split, this meant that runsplit
was always recording three commits, one for each diff hunk, in reverse order
(the base commit was the last diff hunk in the file).
