[PATCH] Fix the fix for PR fortran/90988

[Steve Kargl]

Jeff Law sent me an email that showed my patch for
PR fortran/90988 caused a regression for fixed-form
source code.  The attached patch address that regression.

Briefly, the original patch fixed free-form souce code
parsing for 'PUBLICX' where the required whitespace was
missing (i.e., 'PUBLIC X').  Unfortunately, the regression
is that the original fix did not preserve fixed-form source
code.

OK to commit?
