That feature deserves some documentation at least in the Developers' Guide. This is now ticket #7586 [1]. Users and developers, at least myself, often work with the Sage command line to develop code or modify existing source files. My typical work flow involves having two terminal windows: one to show the Sage command line session; another to show a terminal Emacs session. I would use the command "load" and/or "attach" to (automatically) load the modified source file so that I could experiment with the new code. Of course, there's also the command "iload" to interactively load a file. When using "iload", one has to repeatedly press Enter in order to load the next line in a source file. But the good thing is that for every line loaded with "iload", if the line produces some output then the output is printed as well. One could think of "iload" sort of like individually entering every line at the Sage command line interface. As an aside, there's also the function "edit()" in the Sage library. And now you report about "ed", "%ed" and "%edit" to do a similar thing as described above, but without having to open two terminal windows. Plus, after one is done editing a file, closing the editor would also trigger an automatic reloading of the modified file. That is just awesome to have and I'm grateful to the IPython developers for this nifty feature.
