precompose_utf8: make precompose_string_if_needed() public
commit 5c327502 (MacOS: precompose_argv_prefix(), 2021-02-03) uses the function precompose_string_if_needed() internally. It is only used from precompose_argv_prefix() and therefore static in compat/precompose_utf8.c Expose this function, it will be used in the next commit. While there, allow passing a NULL pointer, which will return NULL. Signed-off-by: Torsten Bögershausen <tboegi@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
