Command suffixes which have special meaning

Some commands like "step", or "list" do different things when an
alias to the command ends in a particular suffix like ">". 

Here are a list of commands and the special suffixes:

list       >
step       +,-,<,>
next       +,-,<,> 
quit       !
kill       !
eval       ?

See help on the commands listed above for the specific meaning of the suffix.
