branch: master
commit 81059cb970f95362eb52d6f53bbf02c70172048b
Author: Katsumi Yamaoka <address@hidden>

    Make TAB and M-TAB run widget-forward and widget-backward (bug#25091)
    
    * lisp/gnus/mm-decode (mm-convert-shr-links): Avoid `shr-next-link'
    and `shr-previous-link' so TAB and M-TAB run `widget-forward' and
    `widget-backward' instead (bug#25091).
