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

Given the following file

[testcompletion.el (application/emacs-lisp, attachment)]

[Message part 3 (text/plain, inline)]

I run
emacs -Q -l ~/tmp/testcompletion.el

then hit the following keys: C-h f m i n i b u f TAB RET 

After "TAB" I get :
minibufferp [Matched]
in the minibuffer.

After "RET" I get a description of `minibuffer-depth' which is totally
unexpected to me. I expected a description of the function `minibufferp'.

I'm assuming that's because of (setq completion-cycle-threshold t).

Apparently, that's because minibuffer-force-complete, called from 
minibuffer-force-complete-and-exit, somehow interprets it as a repeated 
invocation.

Maybe it should examine last-command and do something with it, instead 
of performing the completion-in-region voodoo it's doing now. Or 
minibuffer-force-complete-and-exit should call a non-cycling version.

I tried reproducing this in Emacs 28, and with this test case, Emacs now
selects `minibufferp', so I think this was fixed earlier this year, and
I'm closing this bug report.  If this is still and issue, please respond
to the debbugs address and we'll reopen.
