OK, done, and closing the bug.

Yaron, this change was small enough to accept without copyright
assignment, but if you intend to continue contributing to Emacs (and
we hope you do), I recommend to start your copyright assignment
paperwork rolling at this time.  If you agree, I will send you the
form to fill and the instructions to email it.

Thanks.

Tags: patch

Hello,

Currently, doing emacs -Q and followed by M-x eglot in the scratch
buffer results in a prompt for major mode to manage with LSP, but the
initial minibuffer input as well as the default value for the
completing-read call are both set to the string "nil", which is not very
helpful as that's not a valid input.

This patch tweaks the prompt a little and avoids this issue by leaving
the minibuffer's initial input empty and making sure we don't set the
default value to "nil" either.

Thanks,
Eshel
