Our code supports two regexp flags: AP_REG_ICASE and AP_REG_NEWLINE. Our documentation and widespread usage include not just these, but also AP_REG_EXTENDED and AP_REG_NOSUB, which are ignored in util_pcre.
I presume the unused flags are a historic legacy and can usefully be removed from the docs. But I wonder if they should also be expunged from trunk ap_regex.h, to clean up the legacy? Thoughts? -- Nick Kew
