combinator and combinator3 character limit warnings

[flaggx1]

Could we possibly get a warning message printed to STDERR when the LEN_MAX is exceeded per line 161 in combinator? There has been an issue where this limit is exceeded and combinations are not printing out, but also no warning message is displayed. This could also be implemented into combinatorX where it looks like there is a 64 character limit by default.

Thanks so much for the hard work the hashcat team has put into these tools.
