     *  Bug report by Anon: RCS under Windows 2k:
     * <PRE>
     * In getPageInfo of RCSFileProvider:
     *
     * Problem:
     *
     * With a longer rlog result, the break clause in the last "else if" 
     * breaks out of the reading loop before all the lines in the full 
     * rlog have been read in. This causes the process.wait() to hang.
     *
     * Suggested quick fix:
     *
     * Always read all the contents of the rlog, even if it is slower.
     * </PRE>
