I fiddled with this a bunch.  I think I've come up with a suitable
(if not perfect) solution.  If you choose an option that would, upon
calculating a new spacing, be very close but not _exactly_ the same as
the default -- be it a calculated or .dat-file-driven default -- it will
now 'nudge' the spacing to be the default.

For example, say you had a 20x20 brush with a default spacing of 15.

If the available spacings were therefore calculated to be:

  0, 8, 16, 25, 33, 41, ... 91, 100

Then the third option would actually choose 15, not 16, to be
consistent with the default spacing of the brush.

I'd accept other solutions.  And also, sorry this never occurred
to me when I first added this new feature in 0.9.28.  Thanks for
pointing it out!
