From 7aee804746bb816e0595c06743e16a6100e4c59d Mon Sep 17 00:00:00 2001

Subject: [PATCH] (f90-font-lock-keywords-2): Use override for
 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-abbrev-start): Fix XEmacs compatibility.
