    Note to customizers: the body of the webrev is IDed as SUNWwebrev
    to allow easy overriding by users of webrev via the userContent.css
    mechanism available in some browsers.
    For example, to have all "removed" information be red instead of
    brown, set a rule in your userContent.css file like:
        body#SUNWwebrev span.removed { color: red ! important; }

 # sdiff_to_html
 #
 # This function takes two files as arguments, obtains their diff, and
 # processes the diff output to present the files as an HTML document with
 # the files displayed side-by-side, differences shown in color.  It also
 # takes a delta comment, rendered as an HTML snippet, as the third
 # argument.  The function takes two files as arguments, then the name of
 # file, the path, and the comment.  The HTML will be delivered on stdout,
 # e.g.
 #
 #   $ sdiff_to_html old/usr/src/tools/scripts/webrev.sh \
 #         new/usr/src/tools/scripts/webrev.sh \
 #         webrev.sh usr/src/tools/scripts \
 #         '<a href="https://bugs.openjdk.java.net/browse/JDK-1234567">
 #          JDK-1234567</a> my bugid' > <file>.html
 #
 # framed_sdiff() is then called which creates $2.frames.html
 # in the webrev tree.
 #
 # FYI: This function is rather unusual in its use of awk.  The initial
 # diff run produces conventional diff output showing changed lines mixed
 # with editing codes.  The changed lines are ignored - we're interested in
 # the editing codes, e.g.
 #
 #      8c8
 #      57a61
 #      63c66,76
 #      68,93d80
 #      106d90
 #      108,110d91
 #
 #  These editing codes are parsed by the awk script and used to generate
 #  another awk script that generates HTML, e.g the above lines would turn
 #  into something like this:
 #
 #      BEGIN { printf "<pre>\n" }
 #      function sp(n) {for (i=0;i<n;i++)printf "\n"}
 #      function wl(n) {printf "<font color=%s>%4d %s </font>\n", n, NR, $0}
 #      NR==8           {wl("#7A7ADD");next}
 #      NR==54          {wl("#7A7ADD");sp(3);next}
 #      NR==56          {wl("#7A7ADD");next}
 #      NR==57          {wl("black");printf "\n"; next}
 #        :               :
 #
 #  This script is then run on the original source file to generate the
 #  HTML that corresponds to the source file.
 #
 #  The two HTML files are then combined into a single piece of HTML that
 #  uses an HTML table construct to present the files side by side.  You'll
 #  notice that the changes are color-coded:
 #
 #   black     - unchanged lines
 #   blue      - changed lines
 #   bold blue - new lines
 #   brown     - deleted lines
 #
 #  Blank lines are inserted in each file to keep unchanged lines in sync
 #  (side-by-side).  This format is familiar to users of sdiff(1) or
 #  Teamware's filemerge tool.
