<rant> grml.. can't that !@#$%^&*() platform not at least preserve case
of file names in error output if it already insists to use \ instead of
/ ... but that's consistency, it ensures one can use nothing to paste
and invoke the editor on a different platform.. </rant>

nIndex needs to be initialized for IsNumberFormat(), usually 0 for
current locale and general number format, if it isn't the method assumes
an arbitrary number format it tries to match against if general
detection fails. Fortunately chances are that these arbitrary cases
mostly would fail as well.. fTempValue is initialized in
IsNumberFormat(), either to the number if it could parse some number and
returned true, or to 0.0 if it returned false. However, it doesn't hurt
to initialize also that.

Fixed with;a=commit;h=954ce6f102855be1bd5c84432003d529773b39a8

Thanks for the heads-up
