Bug#101851: apt-get source doesn't honor -m

[Adam Heath <doogie@debian.org>]

I one deb-src line in sources.list, a local mirror.  Today, it had its files
updated during the middle of the daily http.us mirror sync.  I went to install
fetchmail, and apt complained about not being able to install the files(the
normal case where the indices are copied before the files).

I then preceeded to add http.us on a deb-src line, but placed it after the
local mirror.  apt-get source fetchmail again failed, so I added -m to the
command line.  apt still failed, and didn't fall back on the second archive.

If I place the http.us deb-src line first, then apt-get source works.
