Shouldn't it do something when the buffer is modified?

Since browse-url-of-buffer does something similar, the name could be
more descriptive.   Maybe browse-url-of-buffer-external?

"the file of the current buffer."

This is strange.  There are other ways to use an external browser-kind.
Maybe you could use browse-url-secondary-browser-function, which is
"usually an external browser".
