The bug is in the use of $*, not bash. This is a common problem, caused
by a flaw in the design of the original sh.
Change that to
grep() { egrep "$@" ; }
and it will work as expected.
Hey, Brian, maybe you could add a special mode to bash that would
print out warnings for all uses of $* and unquoted variable
references, or maybe someone could write "shlint". ;-)
