Seems fine:
% pz 'repeat $(( 2 + 4 )) (x)'
'repeat'
'$(( 2 + 4 ))'
'('
'x'
')'
% pz 'repeat $( : foo bar; echo 4) (x)'
'repeat'
'$( : foo bar; echo 4)'
'('
'x'
')'
% pz 'repeat "1"'\''2'\''$(( 3 + 0 ))$((echo 4);)\ 5 (x)'
'repeat'
$'"1"\'2\'$(( 3 + 0 ))$((echo 4);)\\ 5'
'('
'x'
')'
Shall I commit this and wait for bug reports?
