[PATCH 0/3] Switch the default PCRE from v1 to v2 + configure fixes

This small series makes USE_LIBPCRE=YesPlease mean USE_LIBPCRE2=YesPlease, instead of USE_LIBPCRE1=YesPlease is it does now. Along the way I fixed a couple of minor issues in the PCRE detection in the autoconf script.

Ævar Arnfjörð Bjarmason (3):
  configure: fix a regression in PCRE v1 detection
  configure: detect redundant --with-libpcre & --with-libpcre1
  Makefile: make USE_LIBPCRE=YesPlease mean v2, not v1
