From ea10b60c910e4a23483f47f17becc5e58f07ebe9 Mon Sep 17 00:00:00 2001 From: Ben Jackson Date: Sat, 18 Apr 2009 20:42:07 -0700 Subject: Work around ash "alternate value" expansion bug Ash (used as /bin/sh on many distros) has a shell expansion bug for the form ${var:+word word}. The result is a single argument "word word". Work around by using ${var:+word} ${var:+word} or equivalent.
