Hi!

When doing an "apt-get install kernel-image-2.6", for example, I get
this:

You should explicitly select one to install.
E: Package kernel-image-2.6 has no installation candidate

But when doing an "aptitude install kernel-image-2.6":

You must choose one to install.
(...)

As you see, apt-get show one kernel-image per line, but aptitude shows 2
packages per line, making difficult to read and choose the kernel to be
installed.

Would be good to show one package per line, and if possible, show also
the version of the package, as apt-get do.

Thank you

Just noting here that these two are very similar but just shy of a
merge.  If you do one and you can pretty easy do the other.

cmdline/cmdline_util.cc (cmdline_show_stringlist and friends) is
roughly where the changes would go.

I took a stab at adding a configuration option for one-package-per-line
output. I'm not sure if adding a configuration option is the best way to
(though it certainly works for me), and I imagine the documentation also
needs to be updated if this is accepted.
