1237                         // - $var or ${var} are expanded to the contents of the named cvar,
1238                         //   with quotation marks and backslashes quoted so it can safely
1239                         //   be used inside quotation marks (and it should always be used
1240                         //   that way)
1241                         // - ${var asis} inserts the cvar value as is, without doing this
1242                         //   quoting
1243                         // - ${var ?} silently expands to the empty string if

1250                         // - when expanding an alias, the special variable name $* refers

1254                         //   parameters, without extra quoting, so one can use $* to just
1255                         //   pass all parameters around. All parameters starting from $n

1257                         // - ${* q} and ${n- q} force quoting anyway
1258                         //
1259                         // Note: when expanding an alias, cvar expansion is done in the SAME step
1260                         // as alias expansion so that alias parameters or cvar values containing
1261                         // dollar signs have no unwanted bad side effects. However, this needs to
1262                         // be accounted for when writing complex aliases. For example,
1263                         //   alias foo "set x NEW; echo $x"
1264                         // actually expands to
1265                         //   "set x NEW; echo OLD"
1266                         // and will print OLD! To work around this, use a second alias:
1267                         //   alias foo "set x NEW; foo2"
1268                         //   alias foo2 "echo $x"
1269                         //
1270                         // Also note: lines starting with alias are exempt from cvar expansion.
1271                         // If you want cvar expansion, write "alias" instead:
1272                         //
1273                         //   set x 1
1274                         //   alias foo "echo $x"
