This is the correct, documented, and historical behaviour for the
'which' script.

Yes, if you're not a csh user it may seem less than optimal... but
it's the way that which has always worked, and changing it will cause
serious problems for people who have gotten used to using it.  (in
particular, if it doesn't source the user's cshrc, it can't
necessarily figure out aliases, etc.)

the ksh equivalent is a shell builtin, 'whence'.
