30.0.50; Open new files very slow if eglot and which-function-mode are enabled. |

Opening C files is very slow if which-function-mode and eglot are
enabled at the same time. I tested this with:
emacs -Q
opening a C project file
M-x eglot
M-x which-function-mode
switching to another .c project file now takes seconds until the buffer
shows up.
I use an old Laptop, but with just one of the two modes disabled,
it's quite snappy.

Thanks, so I added these hints to the doc strings of the two optioins,
and I'm closing the bug.
