The braces `{ ... }` here are unnecessary as `&&`will bind first
(sh and bash give both operators the same precedence but
then use left associativity). Dropping them drops the need for
the semicolon. Of course some might prefer this to be explicit.
The `test` command has AND and OR operators of its own,
which give `-a` (AND) higher precedence than `-o` (OR). In
addition, `$#` can only expand to an integer value, so quotes
are not required, and the whole thing can be written as:
if test $# -ne 1 -a $# -ne 3 -o -z "$1"
(which is what I would do myself, unless I wanted a separate
error message for an empty "$1"). It's fine as is though.
