This patch fixes a broken example in the eglot manual. It makes two
changes:

* Fixes broken function calls
* Slightly simplifies overlay handling

Submitting this upon João Távora's suggestion.

The latest Eglot has this:

(define-obsolete-function-alias 'eglot--uri-to-path 'eglot-uri-to-path "1.16")

The confusion might come from the fact that ELPA had v1.16 for a brief
period, but now (for some strange reason) only v1.15 is available.

Strange indeed.  No idea what happened, but the 1.16 tarball is also
available:

https://elpa.gnu.org/packages/eglot-1.16.tar.lz

Stefan, can you see about this.

Vyacheslav, Felicián is correct.  Don't suggest '--' version of
functions in the manuals.  The remaining simplification is
welcome.  Don't use the symbol name 'inactive--code' though,
the '--' means "private".  That symbol can be "inactive-code"
or 'my-inactive-code' or even 'my-extension--inactive-code'.
Here though, "inactive-code" is preferable for demonstration
purposes.

I'm assuming the scripts bugged out.  I'm copying in the other Stefan,
since he has access to the server where this all runs.

The simplest solution in this case is probably to just bump the version
to 1.17, but that won't stop this from happening again in the future.

Ack. Attached is a small patch that just cleans up overlay handling.

I think the previous run of "update packages" was killed (timeout? OOM?)
and left the Git tree in an incorrect state (more specifically in
a detached state pointing at some old commit where Eglot happened to
still be at 1.15).
I've seen such problem sin the past and have tried to make the scripts
more robust in the face of such weird states, but it's hard to know
how/where to handle it.  I fixed it by hand this time, and added
yet-another sanity check elsewhere to help me catch or fix it, so
hopefully in won't re-occur.

That only works if you Bcc control@debbugs.gnu.org.  I did that here.
