125 * The Quake command-line is super basic. It can be entered in the console
126 * or in config files. A semicolon is used to terminate a command and chain
127 * them together. Otherwise, a newline delineates command input.
129 * In most engines, the Quake command-line is a simple linear text buffer that
130 * is parsed when it executes. In Darkplaces, we use a linked list of command
131 * input and parse the input on the spot.
133 * This was done because Darkplaces allows multiple command interpreters on the
134 * same thread. Previously, each interpreter maintained its own buffer and this
135 * caused problems related to execution order, and maintaining a single simple
136 * buffer for all interpreters makes it non-trivial to keep track of which
137 * command should execute on which interpreter.

1349 // alias foo2 "echo $x"

1355 // alias foo "echo $x"
1356 // "alias" bar "echo $x"
1359 // foo will print 2, because the variable $x will be expanded when the alias
