Upon further thought, the text that I cited in RFC 2369 ("MTAs MUST NOT insert whitespace within the brackets [contained in list header fields]") might not apply to mail user agents, and particularly not to the software library that I referred to in a previous message, which is primarily for mail user agents, not MTAs.

As a result, I declare my question moot.

Subject: Question regarding RFC 2369

RFC 2369 sec. 2 currently says:

   MTAs MUST NOT insert whitespace within the brackets [contained
   in list header fields], but client applications should treat any 
   whitespace, that might be inserted by poorly behaved MTAs, 
   as characters to ignore.
