 The new behaviour seems consistent with what most other utilities do (if
 an error occurs processing an argument, processing continues with the
 next argument but the exit status will be non-zero). POSIX mentions this
 in "Consequences of Errors" in XCU 1.4 Utility Description Defaults.
 Following this for non-standard utilities is not a requirement but makes
 things more consistent.
 
 There is no standard for which(1). The closest is probably the tcsh(1)
 builtin which behaves like the new /usr/bin/which.
 
 There seems little reason to change.
