Subject: [PATCH]         Reviewed by Hyatt

        Fix for this bug:

        <rdar://problem/3915008> REGRESSION (Mail): Too much white space between lines separated by carriage returns

        There are a number of interesting things we could do to fix this bug, including SPI and involving
        the WebKit delegate, etc., however it seems reasonable to start with a hard-coded default that
        will fix the bug in the general case until such time as we can come up with more specific
        solutions.

        So, I added a helper method to create <p> elements with an inline style that sets top and bottom margins
        to 0.1em.

        * khtml/editing/htmlediting.cpp:
        (khtml::InsertParagraphSeparatorCommand::createParagraphElement): New factory method to create
        paragraph elements to insert. Also adds style information to keep the <p> from having "too-big" margins.
        (khtml::InsertParagraphSeparatorCommand::doApply): Call new factory method.
        * khtml/editing/htmlediting.h: Add createParagraphElement() declaration.
