Support Roman month numbers, #'format-time-string src/ChangeLog addition: 2010-09-02 Aidan Kehoe <kehoea@parhasard.net> * strftime.c (roman_upper, roman_lower, strftime): Implement Roman month numbers, as used in central and eastern Europe. * editfns.c (Fformat_time_string): Document two new escapes, to allow uppercase and lowercase Roman month numbers. Remove documentation of a bug that we didn't actually have. * text.h (Qtime_function_encoding): We know the text encoding coming from strftime(), because we always use the one in strftime.c. Don't use Qnative. man/ChangeLog addition: 2010-09-02 Aidan Kehoe <kehoea@parhasard.net> * lispref/os.texi (Time Conversion): Document the new #'format-time-string flags for Roman month numbers.
