Less-technical users are often used to less-technical editors that do NOT try to
be so clever (er, that is, "easy to use").

MS Word, for instance (yes, as far as simple searching is concerned, it can be
considered an editor).  And typical web browsers (whose simple on-page searching
can also be compared here).

You type a space to look for a space, two spaces to look for two spaces,...

Not every search (or even most searches?) by less-technical users is intended to
ignore additional whitespace.  Whitespace can matter to less-technical users
too.  And less-technical does not necessarily mean more sloppy, including about
whitespace between words.
