An unintrusive implementation - no existing interfaces changed, and a single addition for obtaining all of the different long names.
Notes:
* Tests added for the new functionality, and existing tests expanded to take it into account.
* It is now impossible to specify long names with commas in them (but then, that wasn't properly supported before either, more of an oversight).
* The multiple long options are not included in the usage information - just the first one of them is printed

"Add testing for implicit_values and non-consuming of separate tokens."
These commits from 2014 made options with implicit_value set only
consult value in the same token. The problem is that now implicit_value,
a sematic properly, forces a particular syntax, which proved to be
confusing.
function was zero, it was interpreted as no style is suppored. Previously,
it was interpreted as default_styles. Also, remove 'style' argument from
'cmdline' constructors.

options.
