- PCRE2: compile with the ANYCRLF newline convention and DOLLAR_ENDONLY,
as ECMAScript reads '.' and '$'. With PCRE2's default (LF only) '.'
matched the CR of a CRLF line, so regex replace-all deleted CRs.
- Replacement $0 is the whole match, two digits are read greedily and a
group the pattern lacks expands to nothing, as std::regex_replace
(libstdc++) does; these cases are now compared in the tests.
- Plain search visits overlapping matches going forward too, and counts
them, as the backward search found them ('aa' in 'aaa' read 2/1).
- The recovery prompt's replayed content is used on 'y' only if the
journal is unchanged since; otherwise it is replayed again.
- A version 1 journal continued after recovery is rewritten as a
compacted version 2 journal when it needs a chunked checkpoint,
instead of receiving records an older kte would skip. (The version is
read through a separate descriptor: the journal fd is write-only.)
