 Great, I've committed it.  I think I've got Chris' issues fixed too.
 (PR 3951).  I'm doing a bootstrap and test cycle; if it looks good I'll
 post that too.
 
 Then I'll want to make the documentation crystal clear, and hopefully
 figure out a way to add tests to the testsuite.  However, that probably
 requires TCL-hacking, and so might not be doable immediately.  But at
 least we'll have 2.95 and 3.1 agreeing.  I hope there's a 3.0.5; then we
 can consider 3.0 finally fixed too.
 
 [Incidentally, Zack, unless you object I'm going to document cpplib's
 use of environment variables.  I think there are at least 6 we use,
 and some documented only in the code].
