Dscho and Thomas discussed and designed a way to mark "words look like
this" (and anything that are not words are crufts), and Dscho further
argues that it is Ok to discard crufts (which I think is fine).
What you seem to want in this example is "there is no cruft other than
whitespace, but there are different kinds of words". I do not think it is
incompatible with the way crufts are discarded, but it may be incompatible
with the way how words are identified.
I would expect something like:
[a-zA-Z0-9]+|[^ a-zA-Z0-9]+
should define your "two kinds of words". That is, a run of alnums is a
word, and a run of non-alnums is a word, but "matrix[a" is not a word (it
is a sequence of three words "matrix", "[" and "a").
