Intelligently avoid 'wrong' separators in BMenus

[humdinger]

In some situations when you set up the items to be added to a BMenu, it's a hassle to figure out when to add a separator. For example, you may list the files of certain folders, some of them might be empty, and you end up with two separators after another.

Instead of jumping through some hoops to eliminate such 'wrong' separators, is it feasible to have BMenu intelligently remove those before showing the menu?

'Wrong' separators would be:

• The separator is at the very top of the menu.
• The separator is at the very bottom of the menu.
• There's already a separator directly above it (= duplicate separators)
