This adds the new builtin 'string' which supports various string manipulation and matching algorithms, including PCRE based regular expressions. Fixes #2296 Squashed commit of the following: commit 4c3eaeb6e57d76463e9683c327142b0aeafb92b8 Author: ridiculousfish <corydoras@ridiculousfish.com> Date: Sat Sep 12 12:51:30 2015 -0700 Remove testdata and doc dirs from pcre2 source commit b2a8b4b50f2398b204fb72cfe4b5ba77ece2e1ab Merge:11c8a477974aabAuthor: ridiculousfish <corydoras@ridiculousfish.com> Date: Sat Sep 12 12:32:40 2015 -0700 Merge branch 'string' of git://github.com/msteed/fish-shell into string-test commit7974aab6d3Author: Michael Steed <msteed@saltstack.com> Date: Fri Sep 11 13:00:02 2015 -0600 build pcre2 lib only, no docs commiteb20b43d2dMerge:1a09e705f519cbAuthor: Michael Steed <msteed68@gmail.com> Date: Thu Sep 10 20:00:47 2015 -0600 Merge branch 'string' of github.com:msteed/fish-shell into string commit1a09e709d0Author: Michael Steed <msteed68@gmail.com> Date: Thu Sep 10 19:58:24 2015 -0600 rebase on master & address the fallout commita0ec9772cdAuthor: Michael Steed <msteed68@gmail.com> Date: Thu Sep 10 19:26:45 2015 -0600 use fish's wildcard_match() for glob matching commit64c25a01e3Author: Michael Steed <msteed68@gmail.com> Date: Thu Aug 27 08:19:23 2015 -0600 some fixes from review -
