A script's code was cut at the character limit before its ST_Xstring escapes
were decoded, so a script whose escapes (`_x0009_`, `_x000D_`) made the file's
text longer than the limit lost its end without a warning, although its code
fits. The code is now decoded first and then cut one character past the limit,
so a script that is too long once decoded still fails the check and its cell
keeps only its value, as before. Decoding is linear and reads at most a bounded
number of encoded characters, enough for any code that fits.
