      original ``SomeException`` had we allowed it to propagate to the caller.

         try:
             ...
         except SomeException:
             tb = sys.exc_info()[2]
             raise OtherException(...).with_traceback(tb)

The code example with no markup except indents does not work because without a new indent, the last line is merged with the preceding one as part of the same paragraph.

        traceback of the original SomeException had we allowed it to propagate to the caller.

            try:

                …
            except SomeException:

                tb = sys.exc_info()[2] raise OtherException(…).with_traceback(tb)

Note also the uneven line spacing, which is different for me here with Firefox that in the web page (also with Firefox).  Something different is needed, but I do not know what.
