Subject: zone.lisp: Split a single `:txt' string into small enough pieces.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/zone/commitdiff_plain/48c0bf44ad8cdbaf60811f03e08d14caef1964be?ds=inline;hp=48c0bf44ad8cdbaf60811f03e08d14caef1964be

zone.lisp: Split a single `:txt' string into small enough pieces.

The substrings of a `:txt' record can be at most 255 bytes long.  If the
argument is a single string that's too long then split it into pieces;
prefer to split at semicolons, or spaces.

If the argument is a list of strings, then respect their split.
Theoretically, the split positions are semantically transparent, but
it's possible that some programs are sensitive to the boundaries.
