Subject: Makeinfo mishandles defaulted node links

The following example demonstrates a bug in makeinfo:

$ cat top.texi
@setfilename top.info

@node Top
@top Top

@menu
* first::
@end menu

@node first
@chapter first

@menu   @c
* second::
@end menu

@node second
@section second
$ makeinfo top.texi
Making info file `top.info' from `top.texi'.
./top.texi:3: Next field of node `Top' not pointed to.
./top.texi:17: This node (second) has the bad Prev.
makeinfo: Removing output file `/home/as/test/top.info' due to errors; use --force to preserve.

Makeinfo is being confused by the whitespace after @menu, or rather by its
absence.

	* makeinfo/node.c (cm_node): When searching for @menu don't
	require a space after it.
