[Nano-devel] [PATCH 3/3] files: check for an empty FIFO before blocking on it

[Brand Huntsman]

The open() in open_file() blocks if an empty FIFO is opened, causing nano to 
hang. This patch opens the FIFO in non-blocking mode, polls it for data and 
re-opens it in blocking mode if data found. Just start the writing process 
first, and then open nano.

It would also be nice if a "Writing to FIFO..." message was displayed before 
writing to one. It would provide a little feedback as to why nano hangs if the 
FIFO is no longer listening.
