Changes for 2.0b6:
- handle Attic files correctly - this required a change from the old
version (and required touching genmetadata), since we now use the
old RCS archive tree in place (or a copy thereof).
- dolabels now closes the labels journal file explicitly. Previously,
the subsequent "p4d -jr" could see premature eof to due buffered
data, and the last bunch of labels in the dblbls file would not
be converted.
- fix a bug that broke conversion of files that had been deleted and
then re-added in CVS; upon re-adding the file, it would be given
revision #1 agian, instead of the next unused revision number.
- added a couple of test cases for these.
Many thanks to Fan Zhang of Numeritech for helping to wring out
these problems!
