slighly fancier histogram recipe

+feedgnuplot (1.35)
+
+  * replaced a 'say' with 'print'. Should work better with ancient perls
+  * an "exit" command now has effect even with triggered-only replotting
+
+  * More sophisticated handling of termination conditions:
+    - Without --exit, we always end up with an interactive plot when the
+    input data is exhausted or when the user sends a ^C to the pipeline
+    - When streaming, the first ^C does not kill feedgnuplot
+  
+  * Removed threading

+feedgnuplot (1.34)
+
+  * Fix for "Use of implicit split to @_ is deprecated". Thanks to Corey
+    Putkunz
+
+  * Declaring feedgnuplot as a package to let MetaCPAN index this
+    distribution

+
+  * fixed incorrect plotting of --timefmt --rangesize plots

   * Added --rangesize and --rangesizeall. Different curves can now plot

+
+With interactive gnuplot terminals (qt, x11, wxt), the plot windows live in a
+separate process from the main C<gnuplot> process. It is thus possible for the
+main C<gnuplot> process to exit, while leaving the plot windows up (a caveat is
+that such decapitated windows aren't interactive). To be clear, there are 3
+possible states:
+
+=over
+
+=item Alive: C<feedgnuplot>, C<gnuplot> alive, plot window process alive, no
+shell prompt (shell busy with C<feedgnuplot>)
+
+=item Half-alive: C<feedgnuplot>, C<gnuplot> dead, plot window process alive
+(but non-interactive), shell prompt available
+
+=item Dead: C<feedgnuplot>, C<gnuplot> dead, plot window process dead, shell
+prompt available
+
+=back
+
+The C<--exit> option controls the details of this behavior. The possibilities
+are:
+
+=over
+
+=item No C<--stream>, input pipe is exhausted (all data read in)
+
+=over
+

+
+=item C<--exit>
+
+Half-alive. Non-interactive prompt up, and the shell accepts new commands.
+Without C<--stream> the goal is to show a plot, so a Dead state is not useful
+here.
+
+=back
+
+=item C<--stream>, input pipe is exhausted (all data read in) or the

+
+Dead. No plot is shown, and the shell accepts new commands. With C<--stream> the
+goal is to show a plot as the data comes in, which we have been doing. Now that

+
+Note that one usually invokes C<feedgnuplot> as a part of a shell pipeline:
+
+ $ write_data | feedgnuplot
+
+If the user terminates this pipeline with ^C, then I<all> the processes in the
+pipeline receive SIGINT. This normally kills C<feedgnuplot> and all its
+C<gnuplot> children, and we let this happen unless C<--stream> and no C<--exit>.
+If C<--stream> and no C<--exit>, then we ignore the first ^C. The data feeder
+dies, and we behave as if the input data was exhausted. A second ^C kills us
+also.
