 It seems that magma mode in the 4.7 notebook is broken. I observed the
 following session after verifying John Cremona's report about syncing
 problems. I suspect sync is lost due to the multiple commands. Note that
 none of the print commands seem to get executed (no output is observed)
 and that for "print 7;" the line "print 6;" gets echoed (this has probably
 very little to do with the "print 7;" command itself)
 {{{
 a:=1;
 b:=2;
 c:=3;
 ///
 b:=2;
 c:=3;
 }}}

 {{{
 print 4;
 ///
 }}}

 {{{
 d:=4;
 print 5;
 ///
 }}}

 {{{
 print 6;
 ///
 }}}

 {{{
 print 7;
 ///
 print 6;
 }}}
