# We use IFS=: instead of
# for d in `echo ":$PATH:" | sed -e 's/:::*/:.:/g' | sed -e 's/:/ /g'`
# because the latter does not work when some PATH element contains spaces.
# We use a canonicalized $pathx instead of $PATH, because empty PATH
# elements are by definition equivalent to '.', however field splitting
# according to IFS=: loses empty fields in many shells:
# - /bin/sh on OSF/1 and Solaris loses all empty fields (at the
# beginning, at the end, and in the middle),
# - /bin/sh on IRIX and /bin/ksh on IRIX and OSF/1 lose empty fields
# at the beginning and at the end,
# - GNU bash, /bin/sh on AIX and HP-UX, and /bin/ksh on AIX, HP-UX,
# Solaris lose empty fields at the end.
# The 'case' statement is an optimization, to avoid evaluating the
# explicit canonicalization command when $PATH contains no empty fields.
