I like the idea of using a space to match any whitespace in plain
non-regexp isearch.  However, it should be nil by default to preserve
the default behavior for users who don't expect such a change.
Also there should be an easy way to put a literal space into the
search string.  In regexp isearch this can be done with C-q SPC.

One solution is to allow `search-whitespace-regexp' to be a list of
regexps and a new key could rotate this list and search will use
the first element.  I noticed that in most cases as the whitespace
regexp "\\W+" is more useful than "\\s-+".  So a new key could use
the default values '(nil "\\s-+" "\\W+") and switch between them.
