1) The semantics of how "who" command handles the "who hide guilds" and "who
hide ss" settings has changed. Previously when "who hide guilds" was enabled,
it would also disable "who" listing of SS (secret society) type guilds as
well. This has now been changed, to work more logically.
However, this change means that if you wish to also prevent people filtering
you based on your SS's, you need to enable "who hide ss".
2) The venerable "grep" command received some polish, and two new options: -A
<NUM> and -B <NUM>, which work like Unix command GNU grep's similarly named
options; in other words: -A <NUM> will include <NUM> lines of context AFTER a
matching line and -B for BEFORE the matching line.
Example: grep -A 2 -B 5 -i "the " show guilds
This would match lines that have string "the ", ignoring lower/upper case, and
output 5 lines preceeding matching line and 2 lines after it.
