%%bash: read from stream until separator found or buffer is full (#14019)...
%%bash: read from stream until separator found or buffer is full (#14019) Original issue: https://github.com/ipython/ipython/issues/14005 TLDR before we would read line by line however this is not necessary and we should just continue reading until we reach EOF. The case we patch here is if we read a line larger than the allowed buffer size, we will return that chunk (aka the entire buffer) to be written out and still continue reading.

"""Installs the editor that is called by IPython for the %edit magic.
This overrides the default editor, which is generally set by your EDITOR
environment variable or is notepad (windows) or vi (linux). By supplying a
template string `run_template`, you can control how the editor is invoked
by IPython -- (e.g. the format in which it accepts command line options)
Parameters
----------
template : basestring
run_template acts as a template for how your editor is invoked by
the shell. It should contain '{filename}', which will be replaced on
invocation with the file name, and '{line}', $line by line number
(or 0) to invoke the file with.
wait : bool
If `wait` is true, wait until the user presses enter before returning,
to facilitate non-blocking editors that exit immediately after
the call.
