commit 704a178abbf4abec153aae45688fd149ed6f608b
Author: Sébastien Wilmet <swilmet gnome org>

tests textiter: test word boundaries
- As the tests show, some of the functions have a strange and
inconsistent behavior for corner cases.
- Rename test_full_buffer() -> test_search_full_buffer() because
textiter.c is used for other GtkTextIter unit tests.
