Might break on filenames with spaces.

I'd use a python hook, something along those lines (see
man 5 hgrc), should be safer and faster:

hgrc (adapt "hghooks", "buildhook(.py)"):

#v+
[hooks]
commit =
commit.build = python:hghooks.buildhook.mybuild
#v-

buildhook.py:

#v+
from mercurial.node import *

def mybuild(ui=None, repo=None, hooktype='', **args):
    if hooktype != 'commit':
        return True
    files = repo.changelog.read(bin(args['node']))[3]

    # perhaps do a check for removed files and symlinks here
    if files:
        # do stuff with files
#v-
