Here's a last review exercise.  In the file "cities" is a list
of cities with populations and Zip codes.  The following cities
were omitted: add them in alphabetical order
  St. Louis  622,236  MO 63166
  Columbus 539,677 OH 43216
Then, edit the file so that
 (a) the blanks, if any, at the beginnings of lines and
ends of lines are removed.
 (b) each interior string of blanks is replaced by a single tab,
except for the blanks within "Los Angeles", "New Orleans",
"New York", "San Antonio", "San Diego", "San Francisco",
and "St. Louis".
 (c) Spell "Washington" and "Indianapolis" correctly.
Then rewrite the file and type "ready".
