Subject: Bug fix. Ensure that current->cols is initialized
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=d0b3b36a72dcd058687b0018f2b4b82d21e768bb;p=linenoise.git

Bug fix. Ensure that current->cols is initialized

Even when both stdin/stdout are redirected (which prevents the raw mode from getting set).
