Subject: Treat inactive TUI specially in "info win"
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=82e3b5645f9c4edc1d84e57c32665d0e76bbbd77;p=binutils-gdb.git

Treat inactive TUI specially in "info win"

I noticed that "info win" will print the table header, but no windows,
when the TUI is inactive.  This patch changes this to print a message
instead.
