Removed spaces from top-level directory names.

Spaces tend to cause annoyances in a Unix-style shell environment.
This change fixes that.

+# Dice

+# From: BASIC Computer Games (1978)

+#
+# "Not exactly a game, this program simulates rolling
+#  a pair of dice a large number of times and prints out
+#  the frequency distribution.  You simply input the
+#  number of rolls.  It is interesting to see how many
+#  rolls are necessary to approach the theoretical
+#  distribution:
+#
+#  2  1/36  2.7777...%
+#  3  2/36  5.5555...%
+#  4  3/36  8.3333...%
+#    etc.

+#
+# Porting Notes
+#
+#   A fairly straightforward port.  The only change is
+#   in the handling of the user's "try again" response.
+#   The original program only continued if the user
+#   entered "YES", whereas this version will continue
+#   if any word starting with "Y" or "y" is given.
+#
+#   The instruction text--which, like all these ports,
+#   was taken verbatim from the original listing--is
+#   charmingly quaint in its dire warning against
+#   setting the number of rolls too high.  At the time
+#   of this writing, on a fairly slow computer, a
+#   5000-roll run typically clocks in at well under
+#   1/10 of a second!
+#
+#
+# Ideas for Modifications
+#
+#   Have the results include a third column showing
+#   the percent of rolls each count represents.  Or
+#   (better yet) print a low-fi bar graph using
+#   rows of asterisks to represent relative values,
+#   with each asterisk representing one percent,
+#   for example.
+#
+#   Add a column showing the theoretically expected
+#   percentage, for comparison.
+#
+#   Keep track of how much time the series of rolls
+#   takes and add that info to the final report.
+#
+#   What if three (or four, or five...) dice were
+#   rolled each time?
