1366 // parameter is $1 and so on; as a special case, $* inserts all

1368 // pass all parameters around. All parameters starting from $n

1374 // dollar signs have no unwanted bad side effects. However, this needs to

1380 // alias foo "set x NEW; foo2"
1381 // alias foo2 "echo $x"
1383 // Also note: lines starting with alias are exempt from cvar expansion.
1384 // If you want cvar expansion, write "alias" instead:
1387 // alias foo "echo $x"
1388 // "alias" bar "echo $x"
1391 // foo will print 2, because the variable $x will be expanded when the alias
