Fix repeated single-quoting of vm.args values

[nickva]

Previously, values which were parsed from vm.args retained their single quotes when db_set. Later on, in the postinst script, when we replace values in vm.args they got another layer of single quotes.

Fix: #178

do you mean alias stripquote="sed -e 's/^\x27*//' -e 's/\x27*$//'" to remove all the single quotes front and back? currently it just removes one set.

Yes! Good catch, updated the PR

and change sed -i "/^-name/c\-name ${nodename}" /opt/couchdb/etc/vm.args in couchdb.postinst to sed -i "/^-name/c\-name '${nodename}'" /opt/couchdb/etc/vm.args, I think?

that is, ensure $nodename has no single quotes before/after and then set a single pair when we rewrite the -name line.

Good idea, updated
