Something funny seems to be going on with quoted strings. In bash I get this:

:) ~
$ echo "12345" | wc
       1       1       6
:) ~
$ echo 12345 | wc
       1       1       6

But kash gives me this:

/Users/matt.malone$ echo "12345" | wc
       1       0       1

/Users/matt.malone$ echo 12345 | wc
       1       1       6
