Bug#528007: update-exim4.conf only works with LC_ALL=C

[Giuseppe Sacco]

I wrote a small patch for this bug:
===================================================

 UPEX4C_internal_tmp="$(tempfile -m600 -p ex4)"
 
===================================================

but I unsure if a better patch would be check for ${dc_other_hostnames}
for non ascii characters, like in:

===================================================
matches=$(echo "${dc_other_hostnames}" | egrep -c '^[A-Za-z0-9.:@-]*$')
if [ "$matches" -ne 1 ]
then
  error ....
fi
local_domains="$(echo @:localhost:"${dc_other_hostnames}" | \
	sed -e 's|[;: ]*$||' -e 's| *||' -e 's|;|:|g')"
===================================================

Bye,
