[patch,fortran] PR19261 continuation character illegal as first non-blank character in statement

[Jerry DeLisle]

:ADDPATCH fortran:

The attached patch adds warnings for illegal use of '&' in lines.  This follows 
from F95 Standard 3.3.1.3.  With -pedantic errors are given instead of warnings.

I moved the note about the unavailable error machinery to the top of load_line 
since it applies to more than one place in this function.

If someone can figure out how to get that test case to work with the deja-magic, 
I would appreciate it.  Can't get rid of the excess warnings tests with -S

Regression tested and libgomp tested OK.  The libgomp tests require Jacub's 
patch that fixes the PR19260 fix breakage.

OK to commit to 4.2?

Regards,

Jerry
