[PATCH]: PR tui/1995: Ctrl-L refresh in TUI only refreshes currentactive curses window.

[Stephane Carrez <stcarrez at nerim dot fr>]

Hi!

Committed this patch on mainline and 6_4 branch to fix PR 1995.
The CTRL-L was not refreshing the window when the focus was on
the command window.  A work arround existed to refresh it (leave and
re-enter TUI) but it's quite annoying.  The CTRl-L is now handled
even if the focus is on the command window.
