1259                         //
1260                         // Note: when expanding an alias, cvar expansion is done in the SAME step
1261                         // as alias expansion so that alias parameters or cvar values containing
1262                         // dollar signs have no unwanted bad side effects. However, this needs to
1263                         // be accounted for when writing complex aliases. For example,
1264                         //   alias foo "set x NEW; echo $x"
1265                         // actually expands to
1266                         //   "set x NEW; echo OLD"
1267                         // and will print OLD! To work around this, use a second alias:
1268                         //   alias foo "set x NEW; foo2"
1269                         //   alias foo2 "echo $x"
1270                         //
1271                         // Also note: lines starting with alias are exempt from cvar expansion.
1272                         // If you want cvar expansion, write "alias" instead:
1273                         //
1274                         //   set x 1
1275                         //   alias foo "echo $x"
