d9fc3d2a - xgettext: Support message syntax checks

xgettext: Support message syntax checks With this change, xgettext could report common syntactic problems in extracted strings. The current built-in checks are ellipsis-unicode, space-ellipsis, and quote-unicode. Those checks can be enabled with --check option of xgettext and disabled with special "xgettext:" comment in source files. Feature suggested by Philip Withnall in: https://savannah.gnu.org/bugs/?44098 * gettext-tools/src/message.h (enum syntax_check_type): New enum. (NSYNTAXCHECKS): New constant. (enum is_syntax_check): New enum. (struct message_ty): New field 'do_syntax_check'. (syntax_check_name): New variable declaration. * gettext-tools/src/message.c (syntax_check_name): New variable. * gettext-tools/src/msgl-cat.c (catenate_msgdomain_list): Propagate mp->do_syntax_check. * gettext-tools/src/msgmerge.c (message_merge): Propagate ref->do_syntax_check. * gettext-tools/src/msgl-check.h (syntax_check_message_list): New declaration. * gettext-tools/src/msgl-check.c (sentence_end): New function.
