[issue14564] Error running: ( echo 'import os'; echo 'help(os)'; )| python |head

[Peng Yu]

New submission from Peng Yu :

I get the following error when I run the following command. I think that help 
may use something that don't work well with pipe. Could anybody take a look?

~/linux/bin/xplat/src/pymisc/pyhelp/main$ ( echo 'import os'; echo 'help(os)'; 
)| python |head

[issue19155] Display stack info with color in pdb (the "w" command)

[Peng Yu]

New submission from Peng Yu:

Currently, the "w" command does not show the stack info in color. I think that 
it might be visually helpful to add some color to emphasize the current frame, 
etc. May I suggest to add this feature to pdb? Thanks.
