ipython (interactive python) support in GDB/Python

[Kevin Pouget <kevin dot pouget at gmail dot com>]

Hello,

while testing this ipython shell from GDB (cf below/patch mailing
list), I noticed that the commandline is not behaving correctly: the
arrows (history, line modification) don't work, and neither does the
autocompletion, and it's the same for the python debugger, PDB


do you think there might be something feasible to fix it ?


thanks,

Kevin
