Thanks for pointing out this issue.  We use /bin/sh so we're not
running into this issue.  However, I investigated a bit more and found
out that it relates to the use of "local".  See e.g.
http://superuser.com/questions/363444/how-do-i-get-the-output-and-exit-value-of-a-subshell-when-using-bash-e/1103711#1103711
for an explanation.  Fortunately this is easy enough to work around.
