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.
Using "hledgerdev" was a hack to help ensure that tests used a fresh
developer build by default. Now they specify "hledger" again, which fits
better with stack. It's up to the tester to make sure the desired
executable is first in PATH or specified with -w. (Note a couple of
tests currently don't obey -w and will always run "hledger", see addons.test).
In periodic multicolumn balance reports, column headings now show a more
compact description of common periods (years, half-years, quarters,
months, weeks) for better readability and screen space efficiency.
