Code Issues Proposed changes

Detect blank variable in trueorfalse

Browse Source 
As a follow-on to I8cefb58f49dcd2cb2def8a5071d0892af520e7f7, put in
some detection around missing variable-to-test arguments in
trueorfalse.

Correct a couple of places where we were passing in blank strings,
resulting in the default always being applied.

Add test-cases and enhance the documentation a little.
