Avoid errors in completion due to 'completion-regexp-list'
* doc/lispref/minibuf.texi (Basic Completion):
* src/minibuf.c (syms_of_minibuf) <completion-regexp-list>:
Document that global non-nil settings of 'completion-regexp-list'
are not safe.
* lisp/minibuffer.el (completion-pcm--merge-completions): Avoid
errors in 'try-completion' when PREFIX is nil. (Bug#64351)
