I probably won't soon, but I'll add a few comments too.  :)

I wouldn't have a problem, in fact, I'd prefer it, if the default
behavior was to assume any checkout using a tag should *assume* -M rev
with the same rev passed to -r/-j.

The same goes for -D.  CVS should assume the version of the modules
file to use corresponds to the -D argument.  I don't think I would
require the -D functionality for the initial patch, however.  Shane's
patch, given test cases and documentation and assuming -M rev as I
mentioned above, provides enough additional functionality to be
useful.  Let a later patch add the -D functionality.

In both the assumed -r rev and -D rev cases, I wouldn't have a problem
with -M rev allowing an override of the default.  Then -M HEAD could
be used to get the original behavior.

One question to consider, especially given a change of the default
behavior, would be that some users will be suprised by, say, rdiff
which accepts _two_ -r options and currently, I believe, only consults
modules once.

Thanks for the patch!  I've been thinking modules should behave that
way for years.

Cheers,

Derek
