Message 370358 - Python tracker

The new items can be new issues, with 6 maybe the highest priority.  Currently
<stdin>:1: DeprecationWarning: invalid escape sequence \e
becomes
Warning (from warnings module):
  File "<pyshell#0>", line 1
    '\e'
DeprecationWarning: invalid escape sequence \e

For both Shell and Editor input, the Warning Line is not really needed.  For Shell, the fake filename is not needed, nor is the line # and line if somehow otherwise marked.
