I felt a bit undecided from your first mail on, maybe also because
of your mailer, but wanted to post the all-compatible all-shell
quote of and from Robert Elz here.
#@ Round trip quote strings in POSIX shell. E.g.,
#@ set -- x 'a \ b' "foo'" "\\'b\\a\\r\\" Aä
#@ printf "%s: <%s><%s><%s><%s><%s>\n" "$#" "${1}" "${2}" "${3}" "$4" "$5"
#@ saved_parameters=`quote_rndtrip "$@"`
#@ eval "set -- $saved_parameters"
#@ printf "%s: <%s><%s><%s><%s><%s>\n" "$#" "${1}" "${2}" "${3}" "$4" "$5"

# Though slower use a subshell version instead of properly restoring $IFS
# and flags, as elder shells may not be able to properly restore flags via
# "set +o" as later standardized in POSIX, and it seems overkill to handle
# all possible forms of output "set +o" may or may not actually generate.

Of course, if in install.sub there is already your quote function,
that surely is preferred.
