🚀 go-pugleaf

There is one bug report which I submitted which is still
outstanding:  ${1+"$@"} is not expanded correctly if there is a
word with a space in it.

also, the following command works in other shells but not in bash

sed 's/   */\
/g' oldfile

The \-newline pair dissapears.  (In csh, using \\-newline works.)

my apologies to the list readers if these have already been fixed.

Thank you again to bfox, for the neat shell.

skl.
