Subject: libremessages:flag: Fix several things (also librexgettext)

 - Fix a bug where it panicked if given an odd number of sub-headings.
 - Document the the ability to include sub-headings.
 - Fix librexgettext's handling of it.  It only worked correctly for times
   when it was only called once in a program, or when it was only ever
   called with exactly one flag/description pair (and no headings).
