Your patch had mangled spacing around operators.  This seems to be a bug
in recent versions of Thunderbird, possibly related to
<https://bugzilla.mozilla.org/show_bug.cgi?id=571502>.  I was able to
fix it up in this case as the context is obvious, but please avoid
Thunderbird for inline patches or find a way to avoid this bug.
