// - $var or ${var} are expanded to the contents of the named cvar,
// with quotation marks and backslashes quoted so it can safely
// 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 $$x"
//
// because at definition time, $$ will get replaced to a single $.
