Read CPU frequency from sysfs by default
...
Use the more portable sysfs node /sys/devices/system/cpu/cpuX/cpufreq/scaling_cur_freq
to get the CPU frequency.
In case of an error fall back to /proc/cpuinfo .
Also use a fixed width of 4 for the frequency to avoid position jumps
in case the frequency moves in the range 900-1100 MHz.

show selected command wrapped in a separate window
...
For a process with a very long command, especially with many long
command line arguments, inspecting the command and its arguments could
become inconvenient.
Meanwhile htop supports the concept of "screen", or window, which is
extended here to create a dedicated "CommandScreen", making it possible
to display the command of the selected process in a separate window
meanwhile being wrapped into multiple lines.
Another benefit of using a command screen is, the user can navigate
through the wrapped lines of the command and perform actions like
searching and filtering.

Avoid unsigned integer overflow
...
unsigned integer overflows are well-defined, but they might point to a counting issue.
Having the code free of unsigned overflows makes it easier to spot potential bugs.
