This is indeed a purely stylistic concern. Personally, when a line needs to be split around a binary operator I would split after the operator as I think this reinforces the point that the statement isn't finished once the end of the line has been reached. I do this in any language, not just Perl. It was probably taught to me decades ago as a minor technique in aiding clarity and has stayed with me ever since.

With postfix control operators (if, unless, for etc.) it's the other way round as they are more tightly bound to the subsequent clauses (again, subjective). So I might write:

print 'Very looooooooooooooooooooooooooooooooooooooooooooooooooooooooo
+ooooong non-interpolated string costing $many ',
    "and another clause from prog $0\n";

# but

die 'Loooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
+ooooooong exception message'
    if $OMG_ZOMBIES > $max_zombies_allowable;
