The original PCRE 6.1 sources are checked into the tree with the tag
"pcre-6-1" for reference. What we're checking in right now is the original
plus our changes to make it support UTF-16 and at least one other tweak
(vertical tab considered whitespace). Our work to get our changes was
done on "pcre-6-1-branch", with an anchor at "pcre-6-1-anchor" so you can
see the evolution of the UTF-16 changes.
Note also that there was one small change made here that's not on the branch
in pcre_compile.c.
Info.plist: Updated the part of the copyright message that's about PCRE.
JavaScriptCore.xcodeproj/project.pbxproj: Added new PCRE source files,
removed obsolete ones.
pcre/AUTHORS: Updated to PCRE 6.1. Includes credits for Apple's UTF-16
changes, but not the credits for Google's C++ wrapper, since we don't include that.
