mention that tiny files are not compressed, also other typos (#1357)

Came up in a customer issue. Specifically the threshold is 4 kb and
there is no configuration option. (Nor does Klaus want one.)

Worth adding? With how much detail? The threshold choice is because of
typical block size on disk. You will use at least that much anyway so
why bother compressing.

Drive-by fix tacked onto this PR: correct typos in some `mc anonymous`
examples.
