Feature Proposal: Empty IF condition to be regarded valid and false

Motivation

%IF{"" then="THEN" else="ELSE"}% now causes an error because a null string is not a valid condition. In the past, a null string was a valid false condition.

Description and Documentation

Allowing empty condition (to be exact a string matching ^\s*$) and regarding it as false.

Discussion

No-brainer, IMO can be handled as a bug.

I was thinking only about a null string. But strings matching ^\s*$ were regarded as false in the past, I realized. So I modified the description above accordingly.

Makes sense.
