* Open a Python Shell
* Save as session_log.txt
* Type a line of code
* Notice that the asterisk for "unsaved" does not appear

In installed 3.4.1 on Win 7, I *do* get the unsaved * back when typing. It disappears again when I hit return. So on this system, the meaning seems to be 'unsubmitted code'.

Saving in the middle of a line inserts '\n' before saving (but does not submit for execution) and also removes *.

Further experiments reveal that the **s mean 'the undo buffer is not empty'.  Enter
>>> import time; time.sleep(2)
and ** do not disappear until sleep finishes and a new prompt is displayed. Enter a character at the prompt and ** appear. Delete the char and ** stay. Hit ^z (undo) twice and ** disappear. For the final proof, recall the sleep statement and increase the sleep time to at least 5. Hit enter and ^Z enough times during the sleep and the statement and ** both disappear before sleep ends and the new prompt displayded.  The behavior is the same after saving Shell, which adds the name of the file to the title.

Using ** on the title bar to indicate the status of the undo buffer is undocumented as far as I know. I would agree that this is surprising, not very useful, and that having ** mean 'unsaved' for Shell as well as for other windows might be more useful.

A follow-on issue would be to have an option to prompt to save (as with editor windows) or autosave when closing the shell.  A default path might be .idlerc/shellsave.txt.

The 'follow-on' issue is #23666.
