evolve: fix the 'grab' alias to work on Windows

For some reason, the  variable wasn't substituted on Windows in this case.
From the test suite:

   $ hg grab 8
   '' is not recognized as an internal or external command,\r (esc)
   operable program or batch file.\r (esc)

This change seems hacky, but there isn't a readily available example of setting
up a shell alias like this from a python module to know if there is a better
way, and it seems like this is maybe just a convenience for tests, since there
is no documentation for the aliases.


The local copy of run-tests.py appears to predate the Windows support in the
Mercurial repository's version, and fails each test with:

    The system cannot find the path specified.

However, with this change and blacklisting test-simple4server.t, the tests can
(mostly) be run on Windows like so:

    $ ../../hg/tests/run-tests.py --with-hg=../../hg/hg --blacklist windows
    Skipped test-simple4server.t: blacklisted
    Warned test-obsolete.t: no result code from test
    Warned test-tutorial.t: no result code from test
    Warned test-evolve.t: no result code from test
    Warned test-userguide.t: no result code from test
    Warned test-sharing.t: no result code from test
    Warned test-drop.t: no result code from test
    Failed test-prune.t: output changed
    # Ran 41 tests, 1 skipped, 6 warned, 1 failed.
