Ah these are in cspex are they...  Jim, does this mean you've actually
used them?  Perhaps I should take back my comments!

If this is the glyph I think it is, it's not quite a wide Dijkstra
choice in shape (although mathematically it's the same thing as
Dijkstra choice).  The two glyphs are:

   <dijkstrachoice> looks remarkably like [ and ] glued together.

   <oblong> looks like <sqcap> but with the square completed.

<oblong> is used in CSP in conjunction with <sqcap>, so it's quite
important that they look the same.  In particular, then need to be of
the same width since if they're not formulae sometimes don't line up

If this is needed, we should include a large \& as well.
