[patch] fix for checking the command ambiguousness.

[Muhammad Bilal <mbilal@codesourcery.com>]

Hi,

While I was looking the code of 'lookup_cmd_composition' function, I saw
there incorrect command ambiguousness checking.
Actually  'find_cmd' function does not return the CMD_LIST_AMBIGUOUS
macro, whereas  'lookup_cmd_1' function return this macro on the bases 
of 'nfound'
variable and 'nfound' variable determines the command ambiguousness.

So, checking the command  ambiguousness condition with 'nfound' variables
fixes the bug.

OK?
