26. Code for giving up a non-partial match after failing to find a starting
code unit anywhere in the subject was missing when searching for one of a

pcre2_dfa_match(). This was a missing optimization rather than a bug.
27. Tidied up the ACROSSCHAR macro to be like FORWARDCHAR and BACKCHAR, using a
pointer argument rather than a code unit value. This should not have affected
the generated code.
