Change examples to use do instead of map

I originally called my looping construct "map", but maybe "do" is better?

 I like the idea of using a /map/ structure, for instance, wouldn’t it be cool to type something like:
 #+begin_src sh :tangle no
-  map chmod a+x *.org
+  do chmod a+x *.org
 #+end_src
 How would this work without special syntax? Well, eshell sends the =*.org= as a list of files, which we could use as the delimiter. The downside is that we want to list the files, we need to actually /list/ the files, as in:
 #+begin_src sh :tangle no
-  map chmod a+x (list "a.org" "c.org")
+  do chmod a+x (list "a.org" "c.org")
 #+end_src
 Pretty ugly, but what about using =::= as a separator of the /lambda/ from the /list/, like:
 #+begin_src sh :tangle no
-  map chmod a+x :: *.org b.txt
+  do chmod a+x :: *.org b.txt
 #+end_src
 
 Here is my initial function. After separating the arguments into two groups (split on the =::= string), we iterate over the file elements, creating a /form/ that includes the filename.
