Broken substitution

[Warren Togami <wtogami-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

Upstream dhclient writes out \032 instead of a space if multiple search 
domains are specified in dhcpd.conf.  It has been this way for years. 
Debian and Fedora have worked around this by doing the below bash 
substitution.  Upstream has rejected fixing this in dhclient for 
different reasons.

The substitution below works on bash but not dash.

Dillow suggested this method that will work with bash and dash. 
Unfortunately I now noticed that this seems to remove the space between 
search domain entries.

Any suggestions of how we can fix this?
