Interned pathnames propagating bad information

[Daniel L. Weinreb <dlw at MIT-AI>]

I think this is clearly a case for a "sophisticated user" command.  MOST
files, especially those used by non-wizards (that means everybody except
you and a few others) only reside in one package.  I think that Set
Package should change the information in all places and there should be
a special command for the specialized use that you have, with a suitable
name such that it is apparent that it does something unusual (so that
people won't find it with Apropos and assume it is what they want).

Yeah, having Set Package just do an Update Mode Line is probably the
right thing.
