Log Message:

Add description and item:

Currently, while \e saves a single query as one entry, interactive
queries are saved one line at a time. Ideally all queries
whould be saved like \e does.

o Allow multi-line column values to align in the proper columns

If the second output column value is 'a\nb', the 'b' should appear
in the second display column, rather than the first column as it
does now.
