[issue11139] subprocess: Arguments to .bat scripts get interpreted by shell

[Arve Knudsen]

Arve Knudsen <arve.knud...@gmail.com> added the comment:

The non-obvious thing with 8972 is what to do with an argument list when the
'shell' option is True, isn't it? I can't see how it overlaps with my case.
My suggestion is a flag to enable argument protection in Popen, either just
for arguments passed as a list (i.e., like how it's done in 2.6) or maybe
also for the case where you pass the command as a string (I haven't
considered that case yet, since it's not directly interesting to me).

I can actually see that exarkun suggests something along the same lines in
8972: 'implement the cmd.exe quoting rules in a different function from the
MS C runtime rules'.

</div>As noted in issue 8972, it&#39;s not clear what such a mode should 
actually do.  If you have a concrete proposal you could make it, probably on 
the python-ideas mailing list.  But I&#39;m personally not in favor of it; I
