Merged, with the following changes / comments:

This made me laugh. Feel free to stab me for that one.

As per your comment, I removed the ._install holdover from some older
package version (if there are any around still, I'd be amazed)

Funniest typo ever.

I just removed this.  Sure, asserts are nice, but this returns
list->last anyway.  Calling functions can test for validity.

I left this out for now.  While it may turn out messy, I'm not a huge
fan of declarations like this for all internal functions, only when it
actually requires a forward-decl.  Still, it's purely cosmetic, so I
can add it back in if you want.

Odd.  This may be a build error on my part, but libdownload should
require libssl/libcrypto for https support.

I left this file untouched.  Reason being that tonight I'm going to
drop it entirely for alpm_list_t (as per another thread).

Just FTR: pacman3 should be C99 compliant, so declaring the index
variable outside the for loop shouldn't be required, though again,
it's purely cosmetics at this point 8).

Unused.  Removed this.  getcols is used instead.

See code for my additions to this comment.


Other than that it's all cool.  Committing now.
