log: fix --follow null parent not to include revision 0

If p1 is null, ':.' is translated as '0:null'. But rangeset can't handle null,
only revision 0 was visible.  Because 'null' should not be listed implicitly,
"log --follow" (without -r) should be empty if p1 is null.

Test of "hg grep -f" is added for cmdutil.walkchangerevs().

  $ hg init repo
  $ cd repo

  $ touch foo
  $ hg ci -Am 'add foo'
  adding foo

  $ hg up -C null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

this should be stored as a delta against rev 0

  $ echo foo bar baz > foo
  $ hg ci -Am 'add foo again'
  adding foo
  created new head

  $ hg debugindex foo
     rev    offset  length  ..... linkrev nodeid       p1           p2 (re)
