>Description:
when FS is null, awk (nawk) does not split on character boundries
as mawk and gawk do - and this is an important/critical feature in awk
regardless of whether POSIX specifies it or not - and it shouldn't
be too difficult to make nawk do this. good awk scripts break on
nawk for no good reason because of this - it wouldn't hurt anything
to make nawk compatable with mawk and gawk in this regard, and the
coding shouldn't be too difficult with someone familiar with it.
>How-To-Repeat:
$ echo hello | awk -F "" '{ while ( ++i <= NF ) print $i }'
this should produce:
h
e
l
l
o
but with nawk, it produces an error saying FS is null.
>Fix:
NetBSD nawk code needs to be changed.
