I think it should automatically add a #0 terminator. After all, a "CString"
without terminator is somewhat undefined.

In which cases? I think always when a string constant is given where a
"CString" value is expected, whether for a parameter, or a variable
initializer. E.g. the following should work as expected:

var numbers:array[1..3] of cstring value (1:'one';2:'two';3:'three');

or in BP syntax:

const numbers:array[1..3] of pchar=('one','two','three');

Many of my programs rely on this.
