chars, for consistent filling of comment blocks. Use
`match-string-no-properties'.
(f90-break-line): Do not leave trailing whitespace when filling
comments.
font-lock-variable-name-face in declarations (so that strings in
declarations are over-ridden). Highlight continuation characters.
(f90-indent-new-line): Remove direct call to f90-indent-line-no,
f90-update-line, since f90-indent-line calls these.

(f90-procedures-re): Add `null' and `cpu_time' from F95.
(f90-font-lock-keywords-1): Minor reorganization so we don't need
`override' any more.
