+ * awk.h (is_alpha, is_alnum, is_identchar): Add declarations.
+ * awkgram.y (yylex): Use is_alpha.
+ (is_alpha, is_alnum): New functions.
+ (is_identchar): Use is_alnum.
+ * builtin.c (r_format_tree): Use is_alpha, is_alnum.
+ * command.y (yylex): Use is_alpha, is_identchar.
+ * ext.c (is_letter): Use is_alpha.
+ (is_identifier_char): Removed; replaced uses with is_identchar.
+ * main.c (arg_assign): Use is_alpha, is_alnum.
