Change all SMARTLIST_FOREACH loops of >=10 lines to use BEGIN/END

The SMARTLIST_FOREACH macro is more convenient than BEGIN/END when
you have a nice short loop body, but using it for long bodies makes
your preprocessor tell the compiler that all the code is on the same
line.  That causes grief, since compiler warnings and debugger lines
will all refer to that one line.

So, here's a new style rule: SMARTLIST_FOREACH blocks need to be
short.
