m3u8 live window fix

[edward-rafalovsky]

Live window sliding should be independent from the --delete param

Would you make two changes?

1. Remove this line from popleft_panes

        if len(self.panes) >= self.size:

That doesn't need to be there, the size is checked in slide_panes. Which brings us to the second change.

2. Fix my other error in slide_panes This is what slide_panes needs to look like.

    def slide_panes(self, a_pane=None):
        if a_pane:
            self.push_pane(a_pane)                                      
        while len(self.panes) > self.size:
                self.popleft_pane()

Right now I have

    def slide_panes(self, a_pane=None):
        if a_pane:
            self.push_pane(a_pane)
        if self.delete:              # This line is wrong. 
            while len(self.panes) > self.size:
                self.popleft_pane()

If you'll do that for me, I accept the patch and new release.
