It's an interesting idea, and I guess it's pretty trivial to implement?
That is, if `load' is called with an absolute path, then bind
`load-path' and add the directory to the value locally.

It sounds convenient, but also kinda chaotic -- if I load "/tmp/foo.el",
then I may not want to load anything else from "/tmp/" just because
"/tmp/foo.el" says "(require 'bar)".  That is, it sounds kinda insecure.

There's also the issue of being consistent -- today,
'(load "/tmp/foo.el")' and `C-x C-f /tmp/foo.el RET' and then
`eval-buffer' gives the same result...  but this wouldn't be the case if
we changed `load' this way.

Now, we could add a new command `load-file-with-directory' or something
that would do this -- that would be more clear, at least, that we're
playing games with `load-path', and would be almost as convenient as if
`load' did this itself.

Any opinions here?
