(INPUT_BLOCK_SLOP, OUTPUT_BLOCK_SLOP): New macros.
(MAX_BLOCKSIZE): Now accepts an arg. All uses changed.
(page_size): New var.
(scanargs, skip, main): Use more-straightforward way to detect overflow.
(dd_copy): Use page_size rather than invoking getpagesize.
Use INPUT_BLOCK_SLOP, OUTPUT_BLOCK_SLOP.
(main): Set page_size.
Avoid a call to stat in the usual case where ftruncate succeeds.
remove the "=1".
(TIME_SOEC_HOURS, TIME_SPEC_MINUTES): Must be at end now, so put
them there.
(time_spec_string, time_spec): Hours and minutes must be at
start now, so put them there.
(rfc_2822_format): Now a string constant, not a boolean. All uses
changed.
(iso_8601_format, rfc_format): Remove.
(RFC_3339_OPTION): New constant.
(long_options): Add --rfc-3339.
(usage): Add --rfc-3339. Don't mention --iso-8601.
Mention %:z, %::z, %:::z.
(main): Simplify calculation of 'format'; it was getting too hairy
to follow. Add --rfc-3339.
(show_date): Assume format arg is not NULL, which is the case
now. The default code is moved to 'main'. This simplifies things
and allows the default to be calculated just once.
(load_buffer): Don't read from free'd memory
when handling lines longer than the initial buffer length.
(save_to_hold_area): Don't leak the previous hold_area buffer.
Reported by Tristan Miller and Luke Kendall.
* NEWS: Mention this.
(load_buffer): Avoid integer overflow in buffer
size calculations for very long lines.
Store match length in regoff_t,
not int. Assume that negative return values less than -2
represent regoff_t overflow.
(matcher_error): New function.
(SKIP_SOMETHING, find_occurs_in_text): Use it to report matcher errors.
(alloc_and_compile_regex): No longer any need to worry about
int versus size_t mismatch.
other-writable, and sticky-and-other-writable directories.
(indicator_no[]): Add new symbols.
(indicator_name[]): Add corresponding mode strings.
(color_indicator[]): Add an entry for each new mode string.
(print_color_indicator): Honor new types.

Document the default colors for the new strings.

(slack_codes): Add new dircolors mode names.
(ls_codes): Add corresponding two-letter ls mode strings.

encounters an existing destination file, and gets an affirmative
response, then first try to unlink the destination file rather
than simply failing. Suggestion from Karl Berry.
