This is a fairly minor tweak to netcat completion for something that
confused me.
If you have netcat installed as nc but not as netcat and try:
netcat -<tab>
It creates an empty array for the cache. Thereafter, option completion
won't work after nc either. This change uses $#array instead of $+array
but I've also renamed the variable with a _cache prefix to be more in
line with other functions that do caching.
The options could really do with filling out but it would have to be a
mess to handle GNU netcat, traditional netcat, each of the BSDs and
openbsd netcat installed on Linux. And socat is better anyway.
