Is it ever (as opposed to "not always") possible to omit braces?
It sounds as if we encourage the use of statement modifiers, which
certainly is not what I want to see.
You probably would want to mention that opening braces for
"if/else/elsif" do not sit on their own line, and closing braces for
them will be followed the next "else/elseif" on the same line
instead, but that is part of "most of the C guidelines above apply"
so it may be redundant.

It does not make a useful guidance to leave $youmust part
unspecified.
Incidentally, your sentence is a good example of where use of
statement modifiers is appropriate: $youmust is rarely true.
In general:
... do something ...
do_this() unless (condition);
... do something else ...
is easier to follow the flow of the logic than
... do something ...
unless (condition) {
do_this();
}
... do something else ...
*only* when condition is extremely rare, iow, when do_this() is
expected to be almost always called.
