[Message part 1 (text/plain, inline)]

This version takes `eldoc-documentation-strategy`'s `default-value` to set
instead (the previous one may take the buffer-local value).

Another justification for the patch:

If `eldoc-documentation-strategy` is already set before loading the new eldoc,
loading the library will pop this warning up:

```
Warning (defvaralias): Overwriting value of ‘eldoc-documentation-strategy’ by aliasing to ‘eldoc-documentation-function’
```

By setting `eldoc-documentation-function` before defining
`eldoc-documentation-strategy` as alias, we can preserver its value of avoid
this warning.


By the way, why was `eldoc-documentation-strategy` made obsolete instead of
`eldoc-documentation-function`, isn't the latter's usage ough to be warned
against?

The second patch declares the correct obsolete one.
