(cwarn-font-lock-keywords): New function.
Replaces cwarn-font-lock-remove-keywords cwarn-font-lock-add-keywords.
(cwarn-font-lock-match): New macro.
(cwarn-font-lock-match-assignment-in-expression)
(cwarn-font-lock-match-dangerous-semicolon)
(cwarn-font-lock-match-reference): Use it.
Use defvar rather than defconst since it's meant to be settable.
(cperl-syntax-done-to): Don't hardcode 1 as (point-min).
(cperl-fix-line-spacing): Add missing \ in [ t].
(f90-procedures-re, f90-operators-re, f90-hpf-keywords-re): Use regexp-opt.
(f90-keywords-re, f90-keywords-level-3-re): Add `pure' and `elemental'.
(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.

Use tcl-imenu-generic-expression instead of

Change not legally significant.
Add fortran-comment-line-start-skip to comment-start-skip.
(fortran-comment-indent): Keep whole-line comments in column 0.
(fortran-find-comment-start-skip): New arg `all'.
If ALL is nil, make sure we only match comment-start-skip if we
can't match fortran-comment-line-start-skip.
Fix bug that made it return t but without moving point when
matching '!'! (a false-comment followed by a real comment).
(fortran-indent-comment): Use new `all' argument above.
Be careful not to add an incorrect comment-starter like "C"
in comment-column.
(fortran-split-line): When splitting a comment, reuse the comment
starter from the current line rather than fortran-comment-line-start.
(fortran-indent-line, fortran-auto-fill): Simplify thanks to the
cleaner behavior of fortran-find-comment-start-skip.
(fortran-fill): Don't be confused by ! inside a comment.
(fortran-break-line): Minor cleanup and simplification.
