patch: find(1) -regextype should be POSOPT

[Thien-Thi Nguyen]

Greetings findutils hackers,

The docs say -regextype is positional, but using it (from Emacs)
suchwise i see:

  find . \( -regextype egrep -regex './(doc|examples|lib)' -prune -o -type f 
-name '*.c' -exec /tmp/ko '{}' \; \) -exec ls -ld \{\} \;
  find: warning: you have specified the -regextype option after a non-option 
argument (, but options are not positional (-regextype affects tests specified 
before it as well as those specified after it).  Please specify options before 
other arguments.

I believe find/parser.c line 309 should be changed from:

  PARSE_OPTION     ("regextype",             regextype),     /* GNU */

to

  PARSE_POSOPT     ("regextype",             regextype),     /* GNU */

in order to make the warning go away.  Following is a full patch.
Please let me know if there is a better way to achieve this result.

thi
