[OpenSCAD] Fundamental list comprehension behavior recently changed.

[royasutton]

Consider:

echo( version() );
a = "123";
echo ( [ for (i=a) i ] );

For the past several years the result has been:

ECHO: [2018, 6, 1]
ECHO: ["123"]

For the past few days it has been:

ECHO: [2018, 11, 20]
ECHO: ["1", "2", "3"]

Is there a reason for this low-level change? It seems that the type string
has been re-classified.

Yes, that is need so not every low level function needs to
handle strings. Specifically this is introduced along with ord().

See https://github.com/openscad/openscad/pull/2509 and linked
discussions.
