* Parsed command tree.
*
* The parser builds syntax only. It does not expand formats, environment
* variables, or ~, does not evaluate %if/%elif, does not expand aliases, and
* does not build struct cmd or struct cmd_list. Those are execution-time
* operations.
*
* Command failure scope is represented by CMD_PARSE_SEQUENCE: if an invoked
* command or assignment fails, the invoker skips the remaining children of
* that sequence. No explicit group ID is stored in the tree.
