# These tests are for the "special" word boundary assertions. That is,
# \b{start}, \b{end}, \b{start-half}, \b{end-half}. These are specialty
# assertions for more niche use cases, but hitting those cases without these
# assertions is difficult. For example, \b{start-half} and \b{end-half} are
# used to implement the -w/--word-regexp flag in a grep program.
