Thanks, done.

> xref-find-definitions differs from find-tag several ways:
> * find-tag always prompted for a name, with the string at (point) as

> * find-tag allowed partial names.  xref-find-definitions does not.
>   Use TAB after a partial name in a prompt for completion(s).
> * If find-tag finds your tags OK but xref-find-definitions does not, you

Thanks.  Some of this is already in the documentation, other parts
will be if/when the code does what we are discussing now.
