print the event named by a logical name Major Section:  HISTORY
:pe fn   ; sketches the command that introduced fn and
; prints in full the event within it that created fn. See
logical-name.  Pe takes one argument, a logical name, and prints
in full the most recent event corresponding to the name. Pe also
sketches the command responsible for that event if the command
is different from the event itself. See pc for a description of
the format used to display a command. To remind you that the
event is inferior to the command, i.e., you can only undo the
entire command, not just the event, the event is indented
slightly from the command and a slash (meant to suggest a tree
branch) connects them.  Use pe! if you want all events
corresponding to a given name; see pe!.
