Subject: Remove dead code from TUI
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=ace206a5a5d86d8427607fd1af484689c0b23eaf;p=deliverable%2Fbinutils-gdb.git

Remove dead code from TUI

I found some dead code in the TUI -- some using #if 0, and some
commented-out code.  There's no reason to keep this, so this patch
removes it.

	* tui/tui-source.c (tui_source_window::do_scroll_vertical): Remove
