- Accommodate macOS dynamic pipe sizing, avoiding hangs.
- Modify the readline redisplay code to use a buffer offset instead of
the physical prompt length in a multibyte locale to determine whether
to reprint the prompt from column 0 because the cursor is before the
last invisible character in the prompt string.
- Fix readline crash with a prompt that exceeds 256 wrapped lines.
Fix readline redisplay code to print the entire prompt if the first
few characters are identical but part of a terminal escape sequence
and the prompt needs to be redrawn.
- Work around systems including bytes between 128 and 255 in the
isalpha(3) set, which causes bash to potentially include them in
identifier names.
- If readline handles a SIGWINCH and updates its idea of the screen
dimensions, it needs to recompute the columns where the prompt wraps
lines every time, not just when the screen width decreases.
