It would be nice if bash could save and display the directory where a command from its history was run.

I have a patch which adds the path as a string in the `HIST_ENTRY` struct and reads and writes it after the timestamp in the comment line in the history file.

The modified history file looks like:

    #1557421027 /Users/me/projects/bash
    cd lib
    #1557421028 /Users/me/projects/bash/lib
    ls
    #1557421033 /Users/me/projects/bash/lib
    echo i am in lib
    #1557421034 /Users/me/projects/bash/lib
    ls
    #1557421037 /Users/me/projects/bash/lib
    cd readline/
    #1557421038 /Users/me/projects/bash/lib/readline
    ls
    #1557421041 /Users/me/projects/bash/lib/readline
    cd ..
    #1557421042 /Users/me/projects/bash/lib
    ls
    #1557421043 /Users/me/projects/bash/lib
    cd ..
    #1557421044 /Users/me/projects/bash
    echo

The patch doesn't change the output when `history` is run, but having it display the path in parens just before the command would be useful. It also doesn't change any functionality when running a command from the history, but one could imagine having the ability to first change directory of the saved command before re-execution. It also depends on timestamp saving to be turned on as I didn't add a different boolean for cwd path saving. I just wanted to get feedback before going any farther.
