ksh syntax becomes:
function rbenv {
typeset command
`typeset` only declares a local variable if there's an explicit
`function` declaration; otherwise the variable leaks.
Other shells use this syntax:
rbenv() {
local command
This is for dash compatibility, which supports neither `function` nor
`typeset`.
