Mutt showed that line to me as ending:  :=''
(no closing brace, empty value).

If you see that, pipe to a real text-viewer.  The line _is_ well formed,
the variable is being given a default value of one character repeated
three times, that character being 0x26A0, "WARNING SIGN".

Dangers of Unicode, even today.  *sigh*
