All uses changed. + (parse_tab_stop): Renamed from parse_tabstop. All uses changed. + (validate_tab_stop): Renamed from validate_tabstop. All uses changed. + (next_file, main): Check fclose against 0, not EOF. + (expand): Remove unnecessary casts. + Add another loop nesting level, for lines, so that per-line variables + are initialized cleanly. + Revamp tab checking. Check for write error immediately, rather + than just once at the end of the program. + * src/unexpand.c: Lkewise (for the expand.c changes). + (TAB_STOP_SENTINEL): Remove. + (tab_size): Now size_t, not uintmax_t, since we need to store + the sequences of blanks. + (max_column_width): New var. + (usage): Say "blank" where POSIX requires this. + (add_tab_stop): Calculate maximum column width. + (unexpand): Store the pending blanks, instead of merely counting them. + Follow POSIX's rules about -a requiring two blanks before a tab stop. + Get rid of internal label and goto. + * tests/unexpand/basic-1: Fix infloop-3 to match POSIX. + Add blanks-1 through blanks-13. + 2004-08-19 Paul Eggert <eggert@cs.ucla.edu> * NEWS: "chown : file", "chown '' file", and "chgrp '' file" now |
