-h
Locate and remember utilities invoked by functions as those
functions are defined (the utilities are normally located when
the function is executed).
Neither mksh nor ksh93 nor GNU bash (the versions I have on my systems)
even have an option remotely like that. Instead, all three have -h as
trackall (basically, remember utilities when they’re first executed,
instead of only small list (mksh, from pdksh, has cat, cc, chmod, cp,
date, ed, emacs, grep, ls, make, mv, pr, rm, sed, sh, vi and who on the
list to remember if +h, from ksh88 apparently).
In a previous issue this was shaded as optional, but it now is not.
Instead, the real-life existing shells’ -h is an option that needs to
be enabled by default for nōn-interactive shells.
So, where does that rare description for -h stem from, and is it even
historical practice in any shell? Function definition should just do
that IMHO and not do filesystem lookups, just syntactic analysis and
remembering the function itself…

there is no reason to consider using that package)
