Bug Description

This is a feature request from SageDays11.

Add an option for the history from multiple sessions to be merged into one, rather than the current behavior (last session to quit overwrites the file).

The idea would be to have each session periodically save its own history to a common file. Caveat: since now the history file would be shared by multiple sessions, parts of ipython that checkpoint and restore to the history file should restore from a private per-session file rather than the checkpointed one.

This should be probably off by default, since it significantly changes the history behavior and many users may not want it.

Note that shadow history already does part of this - you can't browse
it with cursor-up, but you can grep it with hist -g.

Shadow history isn't well documented. I opened a bug report for it:
