Return to getlog.c CVS log

Up to [local] / src / usr.bin / cvs

Modify the CVSFILE structure using a union to keep information about
both files and directories.  We can now keep the revision number for
regular files, and don't need to fetch the appropriate entry in the
command callbacks.  This saves a huge amount of parsing on Entries
files.
