[Remind-Fans] Please test: Fix for zero-width combining

Hi, Paul,

Ah, thank you.  I have pushed a fix for that into my git repo;
commit a5c9b07052bb21ef3efa773cb797e1129bdda708 in
https://dianne.skoll.ca/projects/remind/git/Remind.git/

In calendar-drawing mode, any whitespace character in the reminder
body is replaced with a single space.  That fixes the box misalignment.

Regards,

Dianne.
