gtk2/gtk/gtktexttag.c
Havoc Pennington 2fab0eb1fa make it a static function 
2000-10-24  Havoc Pennington  <hp@redhat.com>

	* gtk/gtktextview.c (gtk_text_view_scroll_to_mark_adjusted): make
	it a static function

	* gtk/gtktextbtree.c (gtk_text_btree_tag): Gee, maybe we should
	redraw text when a tag is applied to it.

	* gtk/gtktexttag.c (gtk_text_tag_affects_size)
	(gtk_text_tag_affects_nonsize_appearance): private functions to
	see if a tag requires various kinds of redraw/layout to be queued
	up.

	* gtk/gtktexttag.h (struct _GtkTextTag): Remove relief crackrock

	* gtk/testtext.c (fill_example_buffer): Put the cursor
	at the start of the buffer, so search works by default

	* gtk/gtktextiter.c (lines_match): init match_start always

	* gtk/gtktextbuffer.c (gtk_text_buffer_get_iter_at_line_index): New
	function, get iter at a line + a byte index

	* gtk/gtktextiter.c (gtk_text_iter_set_line_index): New function,
	to set byte position within a line
	(gtk_text_iter_check): remove leftover G_BREAKPOINT thing
