use the full spelling of a string literal token so that trigraphs
and escaped newlines don't throw off the offset computation.
On this testcase:
printf("abc\
def"
"%*d", (unsigned) 1, 1);
Before:
t.m:5:5: warning: field width should have type 'int', but argument has type 'unsigned int'
def"
^
after:
t.m:6:12: warning: field width should have type 'int', but argument has type 'unsigned int'
"%*d", (unsigned) 1, 1);
^ ~~~~~~~~~~~~
