| 32 | * You might think that this could be incorporated into regcomp.c, and | |
| 33 | * that would be a reasonable idea... except that this is a generic | |
| 34 | * function (with a generic name), applicable to all compiled REs | |
| 35 | * regardless of the size of their characters, whereas the stuff in | |
| 36 | * regcomp.c gets compiled once per character size. | |
