  After much hassling through the uwm source code and comparing it with
the [roughly] equivalent twm code, I thought I found what the problem was
with it reporting the wrong row/column sizes for xterms: it wasn't
checking for PBaseSize and was always using PMinSize in order to try to
find out what the working area of the window really was (never mind --
it's an ICCCM behavior issue -- I'm just priming the well here.)  But
after making this little ICCM compliance fix, still no go.

  After several hours of staring blindly at the twm and uwm code and
trying to convince myself that there must be some difference between them
because twm worked and uwm didn't I started looking at the library
routines twm and uwm used to get the window size hints.  Or, rather, I
looked at what uwm was using and ran right into the problem.

  Uwm uses XGetSizeHints.  XGetSizeHints masks of all the flags it gets
back from the server except (USPosition|USSize|PAllHints).  It turns out
that PAllHints doesn't include PBaseSize (or PWinGravity for that
matter).  Why doesn't PAllHints include PBaseSize???  Is this a bug??  If
it isn't a bug, how should uwm be getting hints that include PBaseSize?

Not a happy puppy,
