I got an inspiration.  The attached updated patch inserts a space when the '&' 
is missing.  This then catches the case of splitting the token by a continuation 
mentioned in the F95 Standard 3.3.1.3.1:

"If a lexical token is split across the end of a line, the first nonblank 
character on the first following noncomment line shall be an "&" immediately 
followed by the successive characters of the split token."

Regression tested.  I will update the test case continuation_2.f90 appropriately.

OK for trunk?

Jerry
