browse-url and "non-webish" URLs

[Stefan Monnier]

I haven't had time to look into it yet, but I'd like to see the following in
browse-url: if the URL refers to a "text file" then use
url-insert-file-contents (or if url-handler-mode is ON, just use
find-file-other-window).

I often see this when someone posts a URL to an elisp package, which is much
better displayed in an Emacs buffer with highlighting and all than in
a Firefox/w3m.  This also true of URL to patch files, or tarballs.

One problem is that it's generally not easy to tell what is what and
automatically DTRT, so maybe the browse-url buttons should simply offer the
user the choice to pass the URL to an external app, or pass it to the URL
package.

Patches welcome,
