Tabular reports from bal, bs etc. have until now been rendered on
the terminal with one final blank line, for readability.
This change drops the blank line.
This is consistent with the non-tabular balance and register output
(not print, which is a special case), and with most unix commands.
The real reason for it, which I admit is flimsy, is that I can now omit
the final delimiter (>=0) when using shelltestrunner 1.9's new format,
making functional tests easier to maintain and more readable.
If there's opposition, this could be reverted.
