Pipe command into tmux display-popup

[leiteg]

When you pipe a command into tmux popup, the command that runs inside the popup does not the piped contents. For example, consider the following snippet:

outer-command | tmux popup inner-command

I wish that inner-command gets the output of outer-command. Is there any way around that? Also, that would make a great feature to be added in tmux.

You'll need to use temporary file or FIFO or something.
