Author: Daniel Martín <mardani29@yahoo.es>
Commit: Eli Zaretskii <eliz@gnu.org>

    Fix localized display of date and time in the NS port
    
    * src/nsterm.m (ns_init_locale): If not already set, set LC_ALL to the
    current locale ID so that dates, currencies, etc. use the settings
    configured in the operating system.  (Bug#51321)
