Hm; yes.  One can't use zero-width text props (which is how %C is
implemented), so it sets the property on the preceding character.  And
that's not possible when the %C comes first.

Although I guess I could just special-case for that and just leave the
text prop off entirely if it comes first.  That will leave point at
the start of the line.  (Except when there's a colon on the line.)

I changed my mind between writing the mail and writing the code.  It's
"%=".

None of the general specs are described in any of the specific line
format doc strings.
