0.9.0 does a better job of filling blocks in "sequential mode" (which is
what you'll be in when adding lots of documents to a database).  But I'm
not sure that I'd go as far as advising a rebuild.  Running the database
through 'quartzcompact -n' will achieve roughly the same result, but be
a lot faster.

There's also at least "A#", which is Ada for .NET and "F#" which is
OCaml for .NET (I can't help wondering why "F" seemed the obvious

But I'd probably just implement it as a # suffix on a term, since adding
"#" is an obvious way to name a port of something to .NET.  Musical
notes are another example: "D#"

Hmm, we could also check (if a database has been given) that the term
exists, and drop the # if not.  That's probably useful in general, but
also nicely gives us the current behaviour if "C#" hasn't been indexed
with the #.  This check would probably be a useful way to handle + and -
suffixes too...
