Summary:                    xargs in version 1.11.1 has incorrect default for -e
option
Description: 
The (undocumented) -e option for xargs, used to define an argument to be
treated as end of input (sets eof_str), has two problems.

1. The default value is "_".  This means that by default an argument of _
will be treated as end of input.  This is not a nice surprise!

2. The argument is current marked as taking an option value -- which means
that I can't specify an empty string to be end of input, which would
actually be useful.

The patch I attach below fixes both these issues, but does have the
disadvantage of introducing an incompatible change in behaviour.  However,
the current behaviour is both broken and undocumented, so maybe this is
good.
