Collapsing punctuation

[jgm]

I'm baffled about how consecutive punctuation is expected to be handled; the test suite seems to do different things in different places, and often those things seem strange.

For example in affix_WithCommas.txt, ,; seems to collapse to ,, but in punctuation_FullMonty*.txt it stays ,;.

I can't think of a case where I'd actually want to see ,; -- and it seems to me that collapsing to ; makes more sense than collapsing to ,.

Sorry for the delay in responding. (I've turned on notifications now.)

In affix_WithCommas.txt, the comma is the leading character of a user-supplied suffix, and overrides the style-supplied delimiter. The CSL Specification doesn't say anything about user-supplied suffixes, but overriding the delimiter seems the right thing to do there.

In punctuation_FullMontyPlain.txt, both punctuation marks are supplied by the style, so collapsing rules are applied, which mostly just aim to avoid duplicate punctuation. (The controlling map in citeproc-js is here in case it's useful.)
