cdrom-entries in /etc/apt/sources.list have a special
format, that uses square-brackets for delimiting a
string which may contain spaces:
e.g.:
deb cdrom:[blah blah 3.0 blah blah]/ stable ...
stormpkg obviously parses these lines as
space-delimited
tokens and thereby dissects these entries, such that URI
looks like: "cdrom:[blah" and the rest appears
spread over the other fields.
