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).

e1849b79b1 PR/6213: Urban Boquist: /bin/sh does not handle a trapped signal correctly
The problem was that system calls got restarted after a signal,
	 instead of returning EINTR. Thus the read builtin, had no way to
	 know that a signal occured that could change the course of execution.
	 Since the code has sprinkled checks for EINTR all over the place,
	 it is supposed to work properly with non restartable syscalls.
	 The fix is to use siginterrupt(signo, 1), before setting a signal
	 handler, to make sure that system calls don't get restarted.

f33f4be925 Massive fixup:
Rewrite man page in mandoc format rather than nasty man format.
Fix a ton of parsing errors, and generate proper .Xr's.
document all known environment variables.
suggest ksh rather than bash.

The last two fix PR #1966.  Wheee!

Somebody with access to the POSIX spec needs to go in here, and document
our adherence, or lack thereof.

ef88b5d2bd Fixed memory leak on old style command substitution
such as  sh -c 'echo `echo foo`' .
The memory allocated with ckmalloc() at
parser.c:1349:readtoken1() (search for "done:" label)
was never freed.

I changed this to use 'string stack' framework of Ash.
Note that a string on string stack is properly freed on
exception and end of command parsing, and no explicit free
or signal handlings required.
See TOUR for an overview, and memalloc.[ch] for details
of string stack.

cc484b787f The return value of setmode(3) is a pointer to malloc()'ed area
and must be freed to avoid memory leaks if called repeatedly.
The leaks occured on symbolic umask command, such as "umask go-w",
which is undocumented.

d6c354cb4b * remove CFLAGS+=-w for powerpc (added in 1.26):
- it was in the wrong place
	- makefiles shouldn't override CFLAGS; only CPPFLAGS and COPTS
	- christos fixed unsigned char stuff in 1.33 which should
	  remove the need for -w anyway
* move .include <bsd.prog.mk> to EOF
