This is certainly a welcome addition in functionality, but it relies
on the pattern remaining at the start of the PATH (i.e. the user
hasn't played with PATH in any way). Could we not use the
${parameter/pattern/string} parameter expansion instead (e.g.
"${PATH/$NEWPATHS/}") so it doesn't matter whether the user has
further modified the PATH?

Best regards,
