a side effect more clearly show the change in command lines between the
first and second example invocations.

5f72b6ac80 Avoid coredumps if stddev cannot be computed (if all datapoints are identical)
Small cleanup of label printing.

d2f4defee2 Fix the way in which median is calculated. If the data source has even
number of data points, value should be calculated by adding two middle
elements and dividing them by 2.

4a7f3dcea5 In 2003, a -s flag was added to ministat to separate the
avg/median/stddev bars onto separate lines for readability if the
ranges overlapped.  In 2005, ministat was extended to support more than
2 datasets, but the -s code was not updated.  It will coredump if run
with -s and >2 sets.

cd05b0f7a1 dd a '-n' option to ministat, which causes it to display only summary
statistics, not graph and statistical test output.  Useful for automated
processing.

afe98543b8 Add support for more than two datasets. Currently limited to 7 though
the limit is only the number of meaningful graph symbols available.

Statistical comparison is performed between the first dataset and
any further datasets.

avg/median/stddev bars onto two lines.  Useful for datasets that
overlap.

3b9b37bd54 A small statistics tool for gauging the statistical significance
of data from benchmarks etc.  Implements "Student's t" for various
confidence levels, defaults to 95%.

If your benchmarks are not significant at the 95% confidence level,
we don't want to hear about it.
