Coalesced options ending with a value-taking option always fail to parse

[wreedb]

Given the following definition:

include <string>;

class options
{
    bool --something | -s ;
    bool --verbose | -v ;
    std::string --file | -f ;
};

Parsing the following invocation:

./program -svf file.txt

Will result in the following:

missing value for option '-f'

While the following does work:

./program -sv -f file.txt

From my testing, it appears that coalescing works perfectly unless the final option is value-taking.

Yes, we currently only support combining short options for flags. I don't remember the details (I see that was implemented in 2018) but there must be some trickiness about supporting options with values like this.
