Yeah, I think this is way too complex...

No, I dont think it needs to be that complicated.

I think it just needs to skip over all non-numeric until the end; we
only need to deal with strings of the form "c*d+", where we have any
number (including zero) of leading alpha-numerics, followed by at
least one digit. Then we just need to keep the same minimum number of
digits in the increment, and leave the "c*" substring alone.
000123 -> 000124
A999 -> A1000
0A1C999 -> 0A1C1000
I don't think it needs to be any more configurable than this.
