This commit was generated by cvs2svn to compensate for changes in r44852,
which included commits to RCS files with non-trunk default branches.

Import cvs-1.10 onto vendor branch. Merge to follow shortly.

Import cvs-1.9.23 as at 19980123. There are a number of really nice
things fixed in here, including the '-ko' vs. -A problem with
remote cvs which caused all files with -ko to be resent each time
(which is damn painful over a modem, I can tell you). It also found a
heap of stray empty directories that should have been pruned with the -P
flag to cvs update but were not for some reason.

It also has the fully integrated rcs and diff, so no more fork/exec
overheads for rcs,ci,patch,diff,etc. This means that it parses the control
data in the rcs files only once rather than twice or more.

If the 'cvs diff' vs. Index thing is going to be fixed for future patch
compatability, this is the place to do it.
