This patches add `--run` option to the test suites to allow one to run
individual tests out of the test suite.  Like this:

    ./ --run='-4,7,9-12,15-'

Both spaces and commas are accepted as separators for the ranges (In
previous versions only spaces were accepted).

Two previous versions are here:

    [RFC/PATCH] Better control of the tests run by a test suite

    [RFC/PATCH v2] Better control of the tests run by a test suite

In this version I have removed mathematical operators and used ranges as
suggested by Junio[1] and Eric Sunshine[2].


This version also includes changes according to the comments from Eric
Sunshine in the documentation.  But as this version has slightly different
documentation, it would be nice if someone would read it once again :)

Shell patterns are not allowed any more.  I think they are not that useful
and ranges cover almost the same functionality.  Also with patterns like
'[8-9]', it is harder to produce good error messages for invalid range

This conversion is a bit unfinished:

Negation was not necessary for my use cases even in the first version.
I've added it more because it seemed to be very close to the functionality
I was adding and not that complicated.

So, I've left the negation in the new version as well.

I am actually thinking now that --verbose-only= and --valgrind= could be
switched to use the same syntax as in --run.

I also noticed that I am doing the following quite often:

    ./ --run=1-4,27 --verbose-only=27

Maybe it would be better to support 'v' suffix as a flag to indicate what
a test needs to be run in verbose mode:

    ./ --run=1-4,27v
