If only I had read this more carefully when I first opened it, I could
have saved myself hours of painful BIFF-documentation-reading and
bit-by-bit (byte-reversed!) file inspection.  (More comments below.)

Given behavior A (which I independently discovered through much effort
earlier today), I suggest the "tutorial" (de facto manual, available
at python-excel.org as python-excel.pdf) be updated, because it
currently says

"Do not be fooled by the height attribute of the Row class, it does
nothing.  Specify a style on the row and set its font height attribute
instead."

The height attribute certainly does more than nothing when combined
with height_mismatch.  The font-based solution has its merits, but
isn't a perfect substitute for being able to pick a specific row
height.

As a vague idea (weaker than a suggestion), it might be easier, or at
least less cryptic, to add a Row.set_height method and point people to
it in the tutorial, than to explain in the tutorial that they have to
set both height and height_mismatch.

Oh, it might be useful to mention that the reason I was investigating
setting the row height in the first place was because I couldn't coax
Excel into doing automatic height adjustment to accommodate wrapped
text in merged cells.  (As far as I can tell, this is a bug in Excel
2000 and doesn't imply any deficiency in xlwt.)
