[sword-devel] OSIS links

[Karl Kleinpaste]

Summarizing...
a. The regex is a horror.
b. The manual's definition is inconsistent, re: multiples.
c. The () -vs- [] syntax is wrong.
d. Whitespace isn't allowed at all.
e. Ignoring [d], there is a transform to something that ought to work,
   but it's not known whether it actually does work.

So...
1. It's no surprise that the OSIS filters are never complete or correct.
2. And still people wonder that I won't use OSIS up to this point.

Genbooks having whitespace in their keys is /de rigeur/.  Nearly all
genbooks have such keys.  And yet now I learn that there is literally
not supposed to be any way to reference such keys in an osisRef.
