[Bug fortran/31495] New: Is this continuation line legal?

[michael dot a dot richmond at nasa dot gov]

When I compile the program listed below I get the message:

Warning: '&' not allowed by itself in line 4

The other compilers I tried do not print any messages.

PROGRAM print_ascertain
CHARACTER (LEN=20) :: str
str = "Hello world &
& &
&"
END PROGRAM print_ascertain

Confirmed: The relevant section in the standard is 3.3.1.3 .  This diallows a
single '&' by it self on a line, but says nothing about two.  Part of th
eproblem is we treat ' ' (a blank) as non printable in the scanner.
