[PATCH/RFC 0/4] en_US.UTF-8 locale detection

Following discussions[1] about test t9129 UTF-8 locale detection, here's a generic rewrite of the en_US.UTF-8 locale detection to be used with all other tests.

[1] http://thread.gmane.org/gmane.comp.version-control.git/147283

The proposed mechanism could work for system without "locale" command, and would detect en_US.UTF-8 locale when named en_US.utf8 or some other variations.

It must be tested on a wider range of systems (especially non-Linux).

Yann Droneaud (4):
  test: added a library to detect an en_US.UTF-8 locale
  test-lib.sh: added test_utf8() function
  test: use test_utf8 and GIT_LC_UTF8 where an en_US.UTF-8 locale is
    required
  t9129: use "$PERL_PATH" instead of "perl"
