0df4f0ca31 Only do certain actions when we are trully interactive, not just when we 
are connected to a tty:
	1. enable editor
	2. print directory on directory change.
	3. print job messages

b0d51313b4 If we have a script and we are interactive, set interactive to 2. This 
allows us to run scripts with -i without printing the prompt like the

3564ac65d4 Don't hard ignore signals that were ignored by our environment, because 
when we try to set a trap on them it will not work. Also while I am here:
1. don't change the action status if the signal system call failed.
2. don't try to sigignore it if signal failed.
3. clear the signal mask in case our parent blocked it for us.

4e11de6548 Further correct handling of `inpath'. 
The path in the policy is not normalized, and shouldn't be. We accept
only an absolute path, possibly with one trailing slash. Make note of

15ea30eb09 PR/18759: FUKAUMI Naoki: pax/tar dot-dot handling broken 
PR/18840: Frederick Bruckman:  Fix for PR/18663 incomplete pax symlink handling

This patch makes ``--insecure'' do something. Now if ``--insecure''
is not set (the default) we do a realpath(3) in all the pathnames
that we are trying to create and if either realpath fails, or the
path is outside our working directory, we print a warning and die.
This maybe too strict and might fail on valid archives that create
symlinks and directories in the wrong order.

f712e70aee expbackq() was incorrectly backing up a temporary buffer when removing \n 
from the end of output of commands inside $(...) substitutions.
If the program output is n*128+1 bytes long (ending in a \n) then the code
checks buf[-1] for another \n - looking an uninitialised stack.
On a big-endian system an integer of value 10 will satisfy this (unlikely
on little endian) and can happen depending on the last code path to use
a lot of stack!
This caused the problem with newvers.sh on sparc64 after ', 2005' was
added to the date list.
