re PR fortran/42852 (gfortran -Wall warns about truncated lines when only a continuation character is truncated)

2010-07-25  Jerry DeLisle  <jvdelisle@gcc.gnu.org>

	PR fortran/42852
	* scanner.c (gfc_next_char_literal): Move check for truncation earlier
	in the function so that it does not get missed by early exits.
	(load_line): Add checks for quoted strings and free form comments to
	disable warnings on comments. Add check for ampersand as first
	character after truncation and don't warn for this case, but warn if
	there are subsequent non-whitespace characters.
