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
  $ touch unknown

  $ touch a
  $ hg add a
  $ hg ci -m "1"

  $ touch b
  $ hg add b
  $ hg ci -m "2"

Should show unknown

  $ hg status
  ? unknown
  $ hg revert -r 0 --all
  removing b

Should show unknown and b removed

  $ hg status
  R b
  ? unknown

Should show a and unknown

  $ ls
  a
  unknown
