set-alias bug on tcsh

[tboydsto]

The following no longer works on 4.3.0 for tcsh

set-alias brokealias {firefox -new-window "http://an.example.web?&param=one"}

but this does work (removes ?)

set-alias worksalias {firefox -new-window "http://an.example.web&param=one"}

Both the above worked in 4.1.0

Does not work since this change 95c97ef on csh/tcsh and zsh. bash and ksh seem fine. Affects version 4.1.3 and above (last version released is v4.2.4).
