bumped up to 0.10.99.3

2001-08-09  jacob berkman  <jacob@ximian.com>

	* configure.in: bumped up to 0.10.99.3

	* gal/e-text/e-completion-view.c (e_completion_view_init): init
	matches array
	(e_completion_view_destroy): free matches array
	(e_completion_view_disconnect): disconnect from the clear and
	lost_match signals
	(e_completion_view_clear_choices): fixup for ptr array
	(e_completion_view_set_cursor_row): ditto
	(e_completion_view_select): ditto
	(e_completion_view_key_press_handler): ditto
	(clear_completion_cb): handle the clear signal
	(lost_completion_cb): remove a row from the model
	(table_row_count): fixup for ptr array
	(table_value_at): ditto
	(e_completion_view_construct): connect to clear and lost
	completion signals
	(e_completion_view_set_width): ptr array fixup again

	* gal/e-text/e-completion.c (e_completion_class_init): add new
	clean / lost completion signals
	(e_completion_init): initialize the matches array
	(e_completion_destroy): free the matches array
	(e_completion_add_match): fixup for matches being a GPtrArray
	(e_completion_clear_matches): ditto
	(e_completion_clear): new function to clear the list of matches
	(e_completion_foreach_match): fixup for ptrarray
	(e_completion_restart): ditto
	(e_completion_found_match): if we are at the limit return first,
	rather than adding and then unreffing.  there very well could be
	some weird crashes this caused but it is kind of unlikely.
	(e_completion_lost_match): new function to forget about a match
	(e_completion_end_search): add a comment on why this is broken

	* gal/e-text/e-entry.c (e_entry_text_keypress): only start a
	delayed completion if our completion timeout is >= 0.  this
	provides a way for the completion starting / stopping to be
	controlled by something other than the EEntry (ie, file-sel)
