Recently, someone on tech-userlevel pointed out that the csh script for
which(1) is not going to be replaced with a C program or something else.
There are currently 2 open PR's (3191, 13462) about which(1), which
suggests removing/reimplementing the current which(1).  Those PR's were
a reason for me to make a port of a which(1) implementation in C.

So.. what should be done with those PR's?  Can they be closed?
