'list' shows a part of the "currently selected source file".
Whenever the debugger stops, the currently-executing function will become the "currently selected source file".
another 'list' will show the next lines from the source.
...'list <line number>' will show the source around the given line number in the current file.
'list <function>' will show the source of the given function (and make it the "current source").
