christos 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.

christos 6ee2193d9a Reverted to set - turning off -x and -v. Charles corrected me... It is part
of POSIX.

christos ad1f891148 set -
does not anymore clear the -x and -v flags. This was incompatible with
all other bourne shell implementations.

christos 5c42185b5c Oops... typo in the IFS previous fix. 1995-02-28 23:27:24 +00:00
christos 6ab1954578 Changed so that backquote expansion eats all trailing newlines, not just
the last one.
Reported by guido@gvr.win.tue.nl (Guido van Rooij).
Repeat By:

christos 3936aab031 Changed IFS string-splitting so that it breaks spaces even when IFS does not
begin with a space, but contains one. Fixes PR bin/809.

        #!/bin/sh
        list="a  b c "
        echo "With ordinary IFS"
        for i in $list;do
            echo $i
        done
        IFS=":${IFS}"
        echo "With changed IFS"
        for i in $list;do
            echo $i
        done

Note that before the fix ":${IFS}" behaved differently than "${IFS}:".

jtc 4aece6a461 Renamed builtins to builtins.def to eliminate make's (incorrect) circular
dependancy between the builtins data file and builtins.c.

The bug only occured when there was no obj directory, and is a result of
NetBSD's better (compared to 4.4lite's) default make rules.

Fixes bug #301.
