commit d8ab03b03566831cb5dfe8caf4a1e1b77106a342
Author: Sergey Poznyakoff <address@hidden>
Date:   Thu Apr 8 14:25:20 2010 +0300

    Bugfix in mu_rfc2047_decode.
    
    * mailbox/rfc2047.c (mu_rfc2047_decode): Use temporary buffer
    for reading from the filter stream, to avoid preliminary breaking
    from the read loop when end of the buffer is reached. Realloc the
    buffer as neccessary.
