[Feature request] non-operational labels

[vaygr]

It would be nice to have non-operational labels in xmenu for the purpose of creating dialog prompts.

For example: "Close window?", "Yes", "No". The idea is taken from fluxbox:

 [nop] (label) <'icon'>

    Insert a non-operational item into the current menu. This is much like [separator],
but instead of a line, it inserts a label. This can be used to help format the menu into
blocks or sections if so desired. The label is optional, and if omitted a blank item will
be inserted.

In terms of what it could look like in xmenu, maybe prefix non-operational labels with a dot?:

printf '.Confirm?\n\nYes\tyes\nNo\tno' | xmenu

Seems like this has been implemented already in e9c3095, with a slightly different syntax, such as <label>\t:.

Hi. Yeah, it has already been implemented. A description for such behavior was also added on the manual:

The output is the string that will be output after selecting the item. If an item does not have tabs after the label, its label is used as its output. If the output is empty or is a colon (:), the item cannot be selected.

I made colon as an "empty entry" in a previous commit. For example, separators (which are entries without labels) can be specified in the standard input either as an empty line or as a line with only a :.

@phillbush would it be hard to backport that functionality to 4.6.1 as it seems rewrite is still in progress?

Current is not working as expected (for example, keys up/down just close the menu, some xresources changed). I tried to take a look at it yesterday, but didn't succeed. I'm wondering how much effort it would be to patch last stable.

Turns out they were the segfaults:
