Changes:
- Compatibility fix: \bibAnnote and \bibAnnoteFile are provided only
with merging, so they do not conflict with alternative definitions
that are sometimes found in certain BibTeX styles.
Changes:
v8.31a Bug fixes by Arthur Ogawa, so that the new eliding and merging features
do not cause problems with non-REVTeX classes.
v8.31 Bug fix: the merging features of v8.3 are supposed to be
turned off by default but this was not completely right. With
this bug fix, the behaviour without merging is compatible the
earlier versions (<= 8.1).
