Comment 3 for bug 349456

OK, I've implemented the distroseries selector (with auto-default from users reported distroseries), but during review Aaron noticed that we could be using the comments in the sources.list snippet in a way that Ubuntu's software sources '3rd party sources' tab displays them instead of the apt-url.

So, afaics, the 3rd party software tab will display a comment instead of the apt-url line if it appears directly *after* the apt-url - on the same line.

It also appends "(Source code)" to the display of deb-src urls automatically (see bug-349456-sources.png)

Also, it doesn't strip leading spaces from the comment.

For this reason, I've updated the template so that the same comment is displayed after both the binary and source lines, without the leading space.

Now, when this displays inside a pre-element (as it does currently), it forces the browser width to the size of the apt-url lines - which is not optimal. On the other hand, we can a pre-element with the .wrap class - it copy-n-pastes fine - but may also look awkward in the browser window (as it won't necessarily break right where the comment starts).

I also tried continuing an apt-url line over two lines, using '\' and putting the comment on the second line, but software sources does not then pick the comment up.

So, for the moment, I've left the sources.list in a pre (without wrapping). I've attach some screenshots for input.
