[PYTHON MATRIX-SIG] Gist and GNU readline

[Emmanuel Viennet]

 Hi,

GIST seems to be a cool plotting package.
For those like me who can't live without the line editing facilities
from GNU readline, here is a useful patch. I did not make extensive
tests, but it seems to work.

Apply the following diff to the file gistCmodule.c
from  ftp-icf.llnl.gov:/pub/python/busby/pygist-1.0.tgz
Then configure python with readline enabled and recompile.

>  * trick of replacing read() with a gist_read(), but I haven't had a chance
>  * to review the readline source yet.)
