I almost no issues with any of the proposed interfaces. The new
"-Me" syntax is natural. The -Mu syntax also makes sense for all
the standard columns.
The only part that is tricky is the "command + args" column, where
users arguably may want to add/delete "-o" flags, but in general
the various "-o" flags one may want to add are not necessarily
othogonal, and it is not always safe to add such a setting while
unware of its context. So perhaps when changing the command, one
should be forced to use "-Me", but this is not completely obvious.
Perhaps one should be add to insert or delete a "-o" setting, but
this would likely require yet another cinterface (-Mo?) and is likely
not worth the complexity.
