It supports \< and \> out of the box, cf.

https://github.com/laurikari/tre/blob/master/doc/tre-syntax.html

And the darwin patch mentioned above implements [[:<:]] and [[:>:]], see

http://www.opensource.apple.com/source/Libc/Libc-1044.40.1/regex/TRE/lib/tre-parse.c

That patch also implements the REG_STARTEND flag for regexec(3), which
is needed for vi.

Also, tre provides wchar versions for regcomp(3) and friends, so that
nvi wouldn't need its own private regex library anymore.
