Marmaduke Woodman has proposed merging lp:~duke-eml/ipython/ipython-saveappend
into lp:ipython.
Requested reviews:
Registry Administrators (registry)

I have made a small change to allow the magic_save function to append to an
existing file rather than overwrite it.
In using IPython, I often would like to build up a file gradually from the
command line history, and the default behavior of overwriting existing files
makes this difficult, hence the modification.
I haven't written any tests because I don't know how to put one in the testing
framework, but in principle, the test would involve reading an existing file,
running magic_save, then checking the file to see that the intended lines were
appended correctly.
