??? The current master AFAICS already does, but only if you invoke
"C-x v L" with an argument of 1.  Or am I missing something?

(It does so quite naively, though: it just picks up the word at point,
so I've seen it prompting with default being something like
"Copyright".  Perhaps we should use number-at-point instead?)

The command prompts for a directory, so you can type whatever you
want.  Having a fixed default doesn't sound very wise to me (do you
never have to work with several repositories at the same time?), but
I'll defer to Dmitry's opinion here.

Thanks.
