hgutch 836e5e938d Reset SIGCHLD handler to SIG_DFL. 
If run with "-c", both child and parent script processes will handle
SIGCHLD resulting in a possible duplicate "Script done" line in the
output.  This fixes bin/54514.

christos 32f083259b 1. restore the previous finish() logic to make: 
script -e -c /usr/bin/true
	script -e -c /usr/bin/false
   exit with the proper exit code.
2. handle system return value correctly (nabijaczleweli)
3. factor out the conversion of wait status -> shell return code.

christos 503a97f998 PR/55548: Soumendra Ganguly: Since isatty(3) is implemented using 
tcgetattr(3), call it directly to avoid calling it twice. This
makes error handling more precise. Also don't call err(3) when
tcsetattr(3) fails.

christos 4f5bb74d62 PR/55531: Soumendra Ganguly: 
- add more error handling
- handle -p when not a terminal
- call termreset() before printing script done, so that it is printed correctly

Also:
- use ssize_t/size_t instead of int
- use EXIT_SUCCESS/EXIT_FAILURE
- check result of fork() against -1

This patch virtually re-writes the playback code and contains
improvements (mainly the dependency upon BUFSIZ being the same
size as it was wrote at).

OK: christos, joerg

perry 8a49ec08e4 "Utilize" has exactly the same meaning as "use," but it is more 
difficult to read and understand. Most manuals of English style
therefore say that you should use "use".

data interleaved between chunks of actual output (and input), and
teach script how to read the new format so that sessions can be played
back at "proper" time.
