Go ahead, but perhaps edit the PCRE version to 8.35-RC1. We haven't
heard any immediate shouts for bugs in 8.34 (and we know people are
using it) so I guess it's OK to move forwards. Just a couple of
comments, which are not important:
1. I will patch pcre_dfa_exec.c at some point so that its handling of
start_bits is the same as pcre_exec after you have patched it.
2. I will also patch pcretest, which says "starting *byte* set" even
in 16- and 32- bit modes, where the data items are not bytes.
3. It occurs to me that in 16- and 32-bit modes the 32-unit bit maps for
CLASS, NCLASS, and XCLASS have more than 256 bits so could be used to
map more characters. But is this worth the effort?
