2a1ee59131 un-__P functions declared in parser.h. host programs include parser.h,
and so it shouldn't use __P.  (this should probably be done better, by
not declaring the parser functions in headers used by host programs,
but this works well enough.)

1fbf0781c6 Patches from Tor Egge (via Havard Eidnes) to fix various bugs in field
splitting and combining.
(Note: Some of this are not strictly bugs, but differences between traditional
Bourne shell and POSIX.)

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.

6f224ae59f Fix parsing problem introduced in the previous ${10} fix, where $#digit

is not a bad substitution.

340077b543 - fix parsing bug reported by mycroft: ! was only recognized in the beginning
of pipelines. Now we are recognizing it everywhere like ksh, so:

	! if [ a = b ]; then ! echo c && ! true; else ! echo d; fi

  works.

b09ffc42b1 - parser.c: Fix prompting in old style backquote expansion. Fixes PR/2139

- eval.c:   Fix exitstatus invalid resetting in `if' statements were:
		if (exit 3); then
			echo foo $?
		else
			echo bar $?
		fi
	    printed 'bar 0' instead of bar 3

893ade3fac - fix PR1620, -DNO_HISTORY did not work.
- restore parsing state after parsing old style command substitution.
  The ';' in '`echo z;`' broke the following:
	for i in 1; do
		cat > /dev/tty << __EOF__
		`echo z;`
		__EOF__
	done

cVS: Enter Log.  Lines beginning with `CVS: ' are removed automatically

67893cfee5 IEEE 1003.2 (D11.2.2.3) requires that the system's true and false be accessed
instead of searching $PATH.  The best way to satisfy this requirement is to
make them builtins.

True was allready builtin, this patch adds false.
