This function tells you the number of lines that the given string would occupy after final display in a window with a width of <columns>.
This function can be used to determine how many lines a particular string will occupy in particular window. One thing this could be used for is scripting a file pager that will correctly pause between each screen of output, regardless of long lines and SET CONTINUED_LINE|INDENT.
number of lines <string> will occupy if displayed in a window with a width of <columns>, or nothing on error.
$numlines(6 foo bar baz) returns 2 $numlines($word(0 $geom()) foo bar baz) probably returns 1 $numlines(foo bar baz) returns nothing
