Actually this `search-spaces-regexp' thing is rather a feature of word search
intermixed with the pure regexp search into the hybrid half-word/regexp search.

What `C-q SPC' does is adding the invisible regexp `[ ]' to the search string.

In the minibuffer `C-q SPC' could do the same, not necessarily invisibly
because you still see `[ ]' when typing e.g. `C-M-s replace C-q SPC this M-e'
