fixes for #3859. adds options for setting the size of the terminal's rows and columns, and printing the current size.
stty rows <n>
stty columns <n>
orstty cols <n>
stty size
i did add some new
unsafe
blocks, as ioctl calls are needed to get and set terminal size. i couldn't find documentation of what row/col sizes are accepted by GNU'sstty
, but i did some testing and am matching their behavior. i also added tests to confirm this behavior.
