Subject: 	* linespec.c (decode_line_1): Update comments for is_quote_enclosed.
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=eeae0c5010ac7348e156f3845df408710da13100;p=pf3gnuchains%2Fsourceware.git

	* linespec.c (decode_line_1): Update comments for is_quote_enclosed.
	If the filename portion of the linespec was quoted, recheck the
	remainder for additional quoting.
	(locate_first_half): Skip over completer chars, too.
