Suppressing Space Padding of Source Lines
-----------------------------------------

   `g77' should offer VXT-Fortran-style suppression of virtual spaces
at the end of a source line if an appropriate command-line option is
specified.

   This affects cases where a character constant is continued onto the
next line in a fixed-form source file, as in the following example:

     10    PRINT *,'HOW MANY
          1 SPACES?'

`g77', and many other compilers, virtually extend the continued line
through column 72 with spaces that become part of the character
constant, but Digital Fortran normally didn't, leaving only one space
between `MANY' and `SPACES?'  in the output of the above statement.

   Fairly recently, at least one version of Digital Fortran was
enhanced to provide the other behavior when a command-line option is
specified, apparently due to demand from readers of the USENET group
`comp.lang.fortran' to offer conformance to this widespread practice in
the industry.  `g77' should return the favor by offering conformance to
Digital's approach to handling the above example.
