832949b912 When we execute commands from a shell script, make sure that the signals
are being caught (reported by Alexis Rosen), similar to the -c case.

#!/bin/sh
vi "$@"

^C when the script is running...

1666f88d5d Fix the -c problem differently. We cannot just ignore SIGINT etc, otherwise
we cannot interrupt sh -c <command>

9063efaca0 Add -q option, which when used with -v and/or -x, turns off the tracing
during the execution of /etc/profile, .profile and $ENV.

362c3e31c9 The builtin . (dot) command no longer sees the current working directory
even if the specified file is not in the PATH.
This change enforces security and makes it conform to POSIX.

Closes PR #6794.
I thought Christos committed this but not appeared yet. :)

The setstackmark()/popstackmark() pair in dotcmd(), used for freeing
stack storage possibly allocated by find_dot_file(), is redundant for now
since dotcmd() is surrounded by another pair in evalcommand().
This redundancy, however, may help future modifications
(suggested by Christos).

2a9c11dd53 PR/287: Shell does not exit with 126/127 when permission denied/
command not found. Add extra exception type and generalize
	error handling routines to take that exception type. Use
	a global variable exerrno to keep the last exec error.

ff008dabf6 Fix PR/1760, where 'cd -' before any other command could cause a reference
to an uninitialized pointer. Use getcwd() to get the current working directory,
instead of forking /bin/pwd [per Scott's suggestion]

f9382bca1a Fix return builtin to work like it does in ksh:
When not in a function, it skips the rest of the current input file.
Instances of `return' outside function definitions were previously ignored.
What does joe posix have to say about this?

782cb68126 Fix bin/1240, from Dennis Ferguson. the exit builtin with no arguments
should return the exitcode of the previous command but it always returned 0.

58e18fc330 Fixed bug where
$ cat foo
echo $FOO

$ FOO=1 . ./foo
$ echo $FOO

Did not echo 1 at all. Now variable assignments before sourced scripts
are honored during and after the execution of the script.

4fb6f609aa Changed so that syntax errors (EXERROR) set the exit status to 2,
and commands that are not found set the exit status to 1 like all
other bourne shells.
[It used to be 0 and 2 respectively]

036641804e Removed theo's change to check S_ISLNK() for dot commands. This is
unnecessary, since stat() allready resolves symlinks (and fails, if
the link is broken).
