Subject: 2005-01-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* buffer.h: Fix comment on buffer_getstr to reflect that it now
	  uses XMALLOC.
	* buffer.c: (buffer_getstr) Use XMALLOC(MTYPE_TMP) instead of malloc.
	* filter.c: (access_list_remark,ipv6_access_list_remark) Use
	  argv_concat instead of buffer_getstr.
	* if.c: (interface_desc) Use argv_concat instead of buffer_getstr.
	* plist.c: (ip_prefix_list_description,ipv6_prefix_list_description)
	  Use argv_concat instead of buffer_getstr.
	* bgp_filter.c: (ip_as_path,no_ip_as_path) Use argv_concat instead
	  of buffer_getstr.
	* bgp_route.c: (bgp_show_regexp) Fix memory leak: need to free string
	  returned by buffer_getstr.
	  (bgp_show_community) Must use XFREE instead of free on string
	  returned by buffer_getstr.
	* bgp_routemap.c: (set_community) Must use XFREE instead of free
	  on string returned by buffer_getstr.
	* bgp_vty.c: (neighbor_description) Use argv_concat instead of
	  buffer_getstr.
