This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

is a built-in to
|
|
.Xr csh 1 ;
|
|
it allows job specifiers of the form ``%...'' as arguments
|
|
so process id's are not as often used as
|
|
.Nm kill
|
|
arguments.
|
|
See
|
|
.Xr csh 1
|
|
for details.
