asking the user to actually run the recommended commands related
to installation of files such as aliases or login.conf.
* Return to using grep for CVS $Id comparison. Using ident caused too
many problems for people with local CVS/RCS tags in their stuff.
Attempt to make portability a little easier to maintain in spite of
this change by defining the name of the tag to search for. This
is a slightly different change that solves the problem in the PR.

* Adjust a little whitespace
* Make the distrib-dirs/mtree on DESTDIR conditional on user
actually specifying a DESTDIR. This seemed like a safe
way to get the right directories and permissions in the
installed tree since 'make installworld' does the same
thing, but in practice too many people have custom hacks
that we should leave unmolested. Still need to find a way
to deal with 'install -d' and permissions on nonexistent
directories in the middle of the path, but this is at
least no worse that it was before.

process of making the script more cross platform friendly.
* Add -i option to automatically install files that do not exist
on the system already.
* Add the ability to specify DESTDIR.
* Allow the user to specify scripts to run right before the
comparison starts, and when mm is done. This will
allow the user to specify customized local behavior, and
implement features such as automatically deleting files.
* Document the above changes in the man page.
* Switch to using 'ident' for the CVS Id comparison, which
should help with portability, and makes it faster.
* Reorder, and in one case fix some code by doing things in
ways that make more sense.
* Check to see if the file exists on the system before doing
the comparisons. This saves CPU cycles, and streamlines
the auto-install process.
I used bits and pieces of suggestions and patches from various
people, ultimately too numerous to name. Which is not to say
that they were not both appreciated, and helpful in achieving
the ultimate result.
