I used the word "parallel" only in the sense that you first have to
leave the chapter called "Regular Expressions" to find "Regexp
Search".  I didn't mean to suggest this information should not be
divided into separate sections.

My proposal is to include "how to use them" inside the chapter called
"Regular Expressions".  Is there any reason not to do that?

(FWIW, I believe most other programming languages do it like that.)
