Bug#393843: update-exim4.conf fails if user already included "<;"

[Vineet Kumar]

Package: exim4
Version: 4.63-3
Severity: normal


When I upgraded this system from sarge to etch, I had
dc_local_interfaces="<;::1;127.0.0.1"

After the upgrade, I saw messages like:

Malformed IP address "<" in local_interfaces

in my paniclog.  I notice that /usr/sbin/update-exim4.conf now prepends
the "<;" automatically.  Removing that from my update-exim4.conf.conf
works successfully.

Just glancing at the script (I haven't read it all or claim to
understand it all) it looks like it just uses grep to prepend the "<;"
if the string contains any ";" -- that's a bug.  If the user-specified
value begins with "<", the script shouldn't prepend its own "<;".
