Karel interp uses linenrs from flattened source when displaying errors

[gavanderhoorn]

Example:

INTP-368 (PROGNAME, 747) Cannot use specified program
MEMO-073 Program does not exist

There is no line 747 in PROGNAME, or at least, not in the non-preprocessed source of it.

There is probably very little we can do about this as linenrs do not seem to be embedded in the p-code that is generated, but are derived / generated by the pc-loader that is used.

Flattened source does include pre-processor markers that include original line nrs (see #14 for an example), but this is lost in the source->binary transformation (as ktrans.exe does not support any of this).

I just might've found a way around this, as it turns out the linenrs are actually embedded in the p-code. This will require some trickery, but it would seem to be possible.

A problem is that in the case of embedded code (ie: %INCLUDE of a .kl file) it's not clear which line nr should be shown.

Need to investigate what the behaviour of plain ktrans is in such a case.
