Motivation for this change is a verification/fix of the current
truncation reporting/handling.
I checked with debugger and various parameters (including changing
noChars/MAXSTRING) and it's how it currently behaves.

Error messages for truncation are already done in wcmdmain.c around line 1840

/* Handle truncated input - issue warning */
    if (strlenW(extraSpace) == MAXSTRING -1) {
        WCMD_output_asis(WCMD_LoadMessage(WCMD_TRUNCATEDLINE));
        WCMD_output_asis(extraSpace);
        WCMD_output_asis(newline);
    }

Now cmd just outputs a warning but continues on truncated input (don't
know if windows does the same)
