completion-pcm-complete-word-inserts-delimiters is a customizable
variable defined in minibuffer.el.gz.
Value
nil
Documentation
Treat the SPC or - inserted by minibuffer-complete-word as delimiters.
Those chars are treated as delimiters if this variable is non-nil. I.e. if non-nil, M-x SPC will just insert a "-" in the minibuffer, whereas if nil, it will list all possible commands in *Completions* because none of the commands start with a "-" or a SPC.
This variable was added, or its default value changed, in Emacs 24.1.
Probably introduced at or before Emacs version 24.1.
