Hi,

This patch adds a new org-attach-download command, which downloads
remote files with url.el and attaches them with org-attach.  When called
without a prefix, it first looks at point for a link, and prompts the
user for a URL if none is found.  When called with prefix, it prompts
for the URL.  Before downloading, it asks for confirmation.

Thanks,
Adam

Thank you.

Could you also add documentation in the manual for this command?

Don't we already have org-attach-url? I thought that did this...
