Or add 'path:' to it. From 'hg help patterns':

    To use a plain path name without any pattern matching, start it with
    "path:". These path names must completely match starting at the current
    repository root.

$ cd hg/mercurial
$ hg log localrepo.py | wc
   5513   22378  203124
$ hg log mercurial/localrepo.py | wc
      0       0       0
$ hg log path:mercurial/localrepo.py | wc
   5513   22378  203124
