BStringList::Sort with own comparing method.

[dknoto]

I added sorting through his own method of comparing the string.

Testing program.

Please remove files StringList-Test-2.tar.2.xz​ and StringList-Test-2.tar.3.xz. Web+ has some bug.​

As commented in #9267 please use git format-patch to create your patches.

Regarding this patch, intended is a Sort() method with a compare function that operates on const BString& and maybe a second one with const char* parameters. That essentially means avoiding BList::SortItems() and rather using std::sort() directly on BList::Items() with a respective comparison class. That would also be a preferable alternative for the existing Sort() method.

Please mind our coding style guidelines. There should be two blank lines between function definitions.

Okay, these are my first programing steps in this system. I will try to learn the local customs as soon as possible ;-)

Just to avoid a misunderstanding: The patch (though properly formatted now :-)) doesn't address what the TODO intended. The new Sort() method(s) should have a function argument that compares strings. The Sort() method your patch adds works, of course, but it isn't convenient to use.

It seems to me that this approach is difficult. I'm going to develop better version ;-)
