[Bug fortran/42852] New: gfortran -Wall warns about truncated lines when only a continuation character is truncated

["bugs at 59A2 dot org" <gcc-bugzilla at gcc dot gnu dot org>]

gfortran -Wall currently warns about truncated lines even when character 73 is
an ampersand.  Observe item (4) of Note 3.10 in the Fortran 2003 standard:


In some circumstances, for example where source code is maintained in an
INCLUDE file for use in programs whose source form might be either
fixed or free, observing the following rules allows the code to be used
with either source form:

(1) Confine statement labels to character positions 1 to 5 and statements
to character positions 7 to 72;

(2) Treat blanks as being significant;

(3) Use only the exclamation mark (!) to indicate a comment, but do not start
the comment in character position 6;

(4) For continued statements, place an ampersand (&) in both character position
73 of a continued line and character position 6 of a continuing line.
