Subject: 28.0.50; Speedbar cannot recognize complicated imenu index format
Date: Sun, 20 Jun 2021 23:27:18 +0800

According to speedbar manual, it can recognize imenu as tagging
functions. However, I found its imenu support is quite limited. With
more complex form like (NAME . NESTED-SUB-LIST) with customized "go to"
function, I got a malformed error. To reproduce the error, try below
recipe:

1. M-x package-install eglot
2. Install any language server if you havn't. EX: apt install clangd
2. Open a C/C++ project, M-x eglot
3. M-x speedbar

Click on tags in the speedbar frame, and I got a malformed error.

See also https://github.com/joaotavora/eglot/issues/536 (which I report
the same bug to eglot author), I think it will be good to make speedbar
completely support imenu since it's one of the most popular project
navigation tools in Emacs.
