    gdb/doc/gdb.texinfo:2517: warning: `.' or `,' must follow @xref, not `@'.
    gdb/doc/gdb.texinfo:43443: Node `gdb-add-index man' requires a sectioning command (e.g., @unnumberedsubsec).
    gdb/doc/gdb.texinfo:43443: `gdb-add-index man' has no Up field (perhaps incorrect sectioning?).
    gdb/doc/gdb.texinfo:43350: Next field of node `gdbinit man' not pointed to (perhaps incorrect sectioning?).
    gdb/doc/gdb.texinfo:43443: This node (gdb-add-index man) has the bad Prev.
    
    This patch fixes the warnings too.
    
    gdb/doc/ChangeLog:
    
    	* gdb.texinfo (set cwd): Add period.
    	(gdb-add-index man): Move anchor.
