Subject: Fix a linenoise bug when moving off the left
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=fcdee2fc4635a82e4e204a8c0bb63bd5e5858441;p=linenoise.git

Fix a linenoise bug when moving off the left

If the buffer is too big to fit in the window and the cursor
would move off the left edge of the windows, the display
is not shown correctly.
