[m-rev.] diff: fix bug #96

[Julien Fischer]

Fix bug #96, a documentation problem with the parsing_utils module.

library/parsing_utils.m:
 	Fix a mismatch between the order of the arguments in the
 	documentation of predicate identifier/6 and the actual arguments.

 	Minor formatting changes intended to maintain consistency
 	in the library reference guide.

Julien.
