Use cmd_list_element::doc_allocated for Python commands

Browse source 
Python commands manage their "doc" string manually, but
cmd_list_element already has doc_allocated to handle this case.  This
changes the Python code to use the existing facility.

	* python/py-cmd.c (cmdpy_destroyer): Don't free "doc".
	(cmdpy_init): Set "doc_allocated".
