Fix backslash handling in regexp pattern (Bug #37092)
* NEWS: Give an example of how escape sequence processing in single-quoted
regular expressions works.
* libinterp/corefcn/regexp.cc(do_regexp_string_escapes): Rename to
do_regexp_ptn_string_escapes. Only sequence to expand is '\b' for backspace.
Others are handled by PCRE.
* libinterp/corefcn/regexp.cc(do_regexp_rep_string_escapes): New function to
do escape sequence processing for the replacement string since the sequences
to expand differ from that of the regexp pattern.
* liboctave/util/regexp.cc(regexp::replace): Process backslashes in replacement
string so that '\$1' results in '$1' rather than replacement with first
capture buffer.
