history builtin has a -H option to display history entries as they would be written to the history file; history builtin now takes a START-END range specifier for listing; fix stray semicolon when printing shell functions containing a case command; changes to stdin redirection detection in preparation for POSIX interp 1913

- -H: new option, means to display history entries as they would be
written to the history file, with timestamp information and without
line numbers or `*'
- listing now takes a START-END range argument, so you can list a
subset of the history list from START to END, with the format
subject to the -H option. If START > END, list in reverse order.
This moves history and fc functionality closer to convergence
- parse_range: new function, encapsulates parsing START-END history

Display or manipulate the history list.
Display the history list with line numbers, prefixing each modified
entry with a `*'. An argument of N lists only the last N entries.
Without options, or if -H is supplied, display the portion of the
history list specified by RANGE, as described below. If -H is not
supplied, the list displays line numbers, prefixing each modified
entry with a `*'.
When listing or deleting history entries, RANGE is an argument of
the form of a number OFFSET or a range START-END. If OFFSET is supplied,
it references the history entry at position OFFSET; when listing, this
displays the last OFFSET entries. A negative OFFSET is interpreted
relative to one greater than the last history position, so negative
OFFSETs count back from the end of the history list. START and END, if
supplied, reference the portion of the history list beginning at position
START through position END. Negative START and END count back from the
end of the history list. When listing, if START is greater than END,
the history entries are displayed in reverse order from START to END.
Options:
-c clear the history list by deleting all of the entries
-d offset delete the history entry at position OFFSET. Negative
offsets count back from the end of the history list
-d start-end delete the history entries beginning at position START
through position END.
-d range delete the history entries specified by RANGE. RANGE is
described above.
-H display the selected history entries in the format that would
be written to the history file, including any timestamp,
without prefixing any line number or `*'.
-a append history lines from this session to the history file
-n read all history lines not already read from the history file
