b09ffc42b1 - parser.c: Fix prompting in old style backquote expansion. Fixes PR/2139 
and many user complaints why the shell hangs in echo "`"
- 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

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?
[fixes PR/1444]

a45947b2a4 Changed so that 'PATH=newpath command' works, instead of looking at the 
old path. Synced input.c with vangogh.

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]

fbac2e9de2 Fixed new bug the previous fix introduced: 
false
    foo=bar
    echo $?

would print 1
Also fixed the long standing bug:

    false
    echo `echo $?`

would print 0
The exitstatus needs rethinking and rewriting. The trial and error method
is not very efficient

df504509f1 1. Don't core dump on 'fc -l' (From Gerard J van der Grinten) 
2. PATH=xxx ls, does the PATH assignment first and then tries to find ls in xxx
3. VAR=xxx exec ls, does the variable assignment.

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.
