			//   be used inside quotation marks (and it should always be used
			//   that way)
			// - ${var asis} inserts the cvar value as is, without doing this
			//   quoting
			// - ${var ?} silently expands to the empty string if
			//   $var does not exist
			// - ${var !} fails expansion and executes nothing if
			//   $var does not exist
			// - prefix the cvar name with a dollar sign to do indirection;
			//   for example, if $x has the value timelimit, ${$x} will return
			//   the value of $timelimit
			// - when expanding an alias, the special variable name $* refers
			//   to all alias parameters, and a number refers to that numbered
			//   alias parameter, where the name of the alias is $0, the first
			//   parameter is $1 and so on; as a special case, $* inserts all
			//   parameters, without extra quoting, so one can use $* to just
			//   pass all parameters around. All parameters starting from $n
			//   can be referred to as $n- (so $* is equivalent to $1-).
			// - ${* q} and ${n- q} force quoting anyway
			//
			// Note: when expanding an alias, cvar expansion is done in the SAME step
			// as alias expansion so that alias parameters or cvar values containing
			// dollar signs have no unwanted bad side effects. However, this needs to
			// be accounted for when writing complex aliases. For example,
			//   alias foo "set x NEW; echo $x"
			// actually expands to
			//   "set x NEW; echo OLD"
			// and will print OLD! To work around this, use a second alias:
			//   alias foo "set x NEW; foo2"
			//   alias foo2 "echo $x"
			//
			// Also note: lines starting with alias are exempt from cvar expansion.
			// If you want cvar expansion, write "alias" instead:
			//
			//   set x 1
			//   alias foo "echo $x"
			//   "alias" bar "echo $x"
			//   set x 2
			//
			// foo will print 2, because the variable $x will be expanded when the alias
			// gets expanded. bar will print 1, because the variable $x was expanded
			// at definition time. foo can be equivalently defined as
			//
			//   "alias" foo "echo $$x"
