1336                         // - when expanding an alias, the special variable name $* refers
1337                         //   to all alias parameters, and a number refers to that numbered
1338                         //   alias parameter, where the name of the alias is $0, the first
1339                         //   parameter is $1 and so on; as a special case, $* inserts all
1340                         //   parameters, without extra quoting, so one can use $* to just

1344                         // Note: when expanding an alias, cvar expansion is done in the SAME step

1346                         // dollar signs have no unwanted bad side effects. However, this needs to
1347                         // be accounted for when writing complex aliases. For example,
1348                         //   alias foo "set x NEW; echo $x"
1349                         // actually expands to
1350                         //   "set x NEW; echo OLD"
1351                         // and will print OLD! To work around this, use a second alias:
1352                         //   alias foo "set x NEW; foo2"
1353                         //   alias foo2 "echo $x"
1354                         //
1355                         // Also note: lines starting with alias are exempt from cvar expansion.
1356                         // If you want cvar expansion, write "alias" instead:
1357                         //
1358                         //   set x 1
1359                         //   alias foo "echo $x"
1360                         //   "alias" bar "echo $x"
1361                         //   set x 2
1362                         //
1363                         // foo will print 2, because the variable $x will be expanded when the alias
1364                         // gets expanded. bar will print 1, because the variable $x was expanded
1365                         // at definition time. foo can be equivalently defined as
