patch 7.4.1992

Browse Source 
Problem:    Values for true and false can be confusing.
Solution:   Update the documentation.  Add a test.  Make v:true evaluate to
            TRUE for a non-zero-arg.

*TRUE* *FALSE*
For boolean operators Numbers are used. Zero is FALSE, non-zero is TRUE.

*non-zero-arg*
Function arguments often behave slightly different from |TRUE|: If the
argument is present and it evaluates to a non-zero Number, |v:true| or a
non-empty String, then the value is considere to be TRUE.
Note that " " and "0" are also non-empty strings, thus cause the mode to be
cleared. A List, Dictionary or Float is not a Number or String, thus
evaluates to FALSE.
