[issue1399] fnmatch(3) escapes '0' to '\'

Suppose that we supply fnmatch(3) with a pattern of the form "\" (that is '\'
followed by '0') without setting the FNM_NOESCAPE flag. Wouldn't the normal
thing to do is escape the terminating character and return just '0' ? Instead
'\' is returned. As if one has provided a pattern "\\".
I guess that also happens for any other trailing \.  In this case I'd keep 
the current behavior, because I'd expect more the \ to be used, than it to 
just disappear.
