From: Peter Maydell <[email protected]>
Unfortunately the OpenBSD pdksh does not like brackets inside
the right part of a ${variable+word} parameter expansion:
$ echo "${a+($b)}"
ksh: ${a+($b)}": bad substitution
though both bash and dash accept them. In any case this line
was causing odd output in the case where nettle is not present:
nettle no ()
(because if nettle is not present then $nettle will be "no",
not a null string or unset).
Rewrite it to just use an if.
This bug was originally introduced in becaeb726 and was present
in the 2.4.0 release.
