* hippie-exp.el: Renamed from hippie.el.

* hippie-exp.el: Renamed from hippie.el.

	Changes from Anders Holst, to bring hippie-expand up to version 1.2:
	* hippie-exp.el (hippie-expand-max-buffers): New variable.
	(try-expand-line-all-buffers, try-expand-list-all-buffers,
	try-expand-dabbrev-all-buffers): Use it.
	(try-expand-list, try-expand-list-all-buffers): New functions.
	(he-string-beg, he-string-end, he-search-loc): These values are
	now markers, not integers.  Uses changed.
	(he-reset-string, he-substitute-string): Use a marker to preserve
	the old position of point.
	(try-expand-all-abbrevs): handle case the same way as the
        usual expand-abbrev (which is not a very good way, but for
        consistency...).
	(he-dabbrev-beg): Use `skip-syntax' instead of `skip-chars', to
        adjust its behavior to different modes.
	(hippie-expand): Don't messages which try function it is using,
        when the expansion itself is done in the minibuffer (it was very
        annoying to have the message obscuring the expansion).
	(try-complete-file-name, try-complete-file-name-partially,
	try-complete-lisp-symbol, try-complete-lisp-symbol-partially,
	try-expand-line, try-expand-line-all-buffers,
	try-expand-all-abbrevs, try-expand-dabbrev,
	try-expand-dabbrev-all-buffers): No unnecessary "resetting" of the
	epansion, when no expansion is done (caused the buffer to be
	marked as changed, although nothing was done, among other things).
	(he-reset-string): Undoing of last expansion at a later occasion, now
        undoes correctly (before, it garbled things up).
	(make-hippie-expand-function): now uses "(function ...)"
        instead of "'" (matters for compilation).
	(try-expand-line, try-expand-line-all-buffers,
	he-line-search-regexp): uses `comint-prompt-regexp' instead of
	`shell-prompt-pattern', to strip off prompt in process buffers.
