Fix incorrect uses of en-dashes and em-dashes in the intro.

Browse source 
* doc/ref/intro.texi (Introduction): Use commas instead of en-dashes
  around "for example".  Use em-dashes instead of en-dashes around
  parenthetical phrases.  Remove spaces around em-dashes.

Guile is designed for this kind of interactive programming, and this
