We could support both > -C (no args) and -C=20 syntax. Actually, optional numeric arguments are the norm not exception. Think of "diff -u" vs "diff -u20" for example. Also I think it is conventional not to use = for single-letter single-dash options, so -C (no args -- use the default number of the implementation whatever it is) and -C20 (the same behaviour in principle as -C, but use my number instead of the default) are sane, while -C=20 _is_ odd. Having said that, I think abbreviating -u20 -n -r to -u20nr going too far (-nru20 would be palatable perhaps), even if the implementation allows such, unless you are entering "obfusucated command line parameters" contest.
