2f975ba49d tload: fix lockup
It looks like an off by one error was added to tload a couple years
ago while removing goto statements.  This causes tload to go into
an endless loop when the load is just under a scale change integer.
eg: .99, 1.99, 3.99, 7.99

to reproduce you can add, just under the loadavg at line 170 in tload.c:
av[0] = 1.99;

or get the load to that level separately.

The patch below makes the code more like the original, but without the
goto statements.  This can also be fixed by just changing line 183 in
tload.c from "if (0 < row)" -> "if (0 <= row)".

6437aa08d4 Update options to single strings
To assist the translators, each option is a separate string.
This means if we add/change/delete an option the remaining ones
will just keep working and only the impacted option needs some
translation work on it.

7888f6a679 miscellaneous: clean up trailing whitespace once again
An earlier commit attempted to cleanse our environment
of all useless trailing whitespace. But the effort did
not catch 'empty' lines with a single space before ^J.

This commit hopefully finishes off the earlier effort.
In the meantime, let's pray that contributors' editors
are configured so that such wasted crap is disallowed!

042776e04c configure: check for program_invocation_name
For portabiliy, check for program_invocation_name during configure and
define HAVE_PROGRAM_INVOCATION_NAME accordingly. Use of this symbol is
now enclosed with the appropriate #ifdef block.

The symbol program_invocation_name is only used for error message
handling using error(), so it's safe to omit this if it is not
available.

fb11e1fe0a Changed the err and warns to macros
err and warn are BSD format but they are not recommended by library
developers.  However their consiseness is useful!

The solution is to use some macros that create xerr etc which then
just map to the error() function.  The next problem is error() uses
program_invocation_name so we set this to program_invovation_short_name

This is a global set but seems to be the convention (or at least errors
are on the short name only) used everywhere else.
