(Tracing): this new section, its former contents, and... (Understanding): this new section. * src/getargs.h, src/getargs.c (verbose_flag): Remove, replaced by... (report_flag): this. Adjust all dependencies. (report_args, report_types, report_argmatch): New. (usage, getargs): Report/support -r, --report. * src/options.h (struct option_table_struct): Rename as.., (struct option_table_s): this. Rename the `set_flag' member to `flag' to match with getopt_long's struct. * src/options.c (option_table): Split verbose into an entry for %verbose, and another for --verbose. Support --report/-r, so remove -r from the obsolete --raw. * src/print.c: Attach full item sets and lookaheads reports to report_flag instead of trace_flag. * lib/argmatch.h, lib/argmatch.c: New, from Fileutils 4.1.
