If there are only three relevant strategies, then my comments are
irrelevant.  I just wasn't sure.  I wasn't sure that movemail offered
only 2 choices since I hadn't yet looked carefully enough to be
certain that there weren't some combinations #ifdefs that would allow
hybrid strategies like "flock then dotlock" or the reverse, on some
platforms, and I also didn't know if local admins might need (or if we
cared to try to support) custom policies.  If we were using elisp,
then we wouldn't have to decide, since customization would be easy,
but since we're probably not, we'll need to make sure we provide a
complete set of strategies.

However, if movemail only needs (and allows) two strategies normally,
and if adding support for liblockfile to that set then covers all the
relevant cases, then we should be OK.
