updates to release 2.8 from someone else.
To combine the updates to 2.8 and your changes between 2.8 and 3.4,
put the updates to 2.8 into file f.c and execute
rcsmerge -p -r2.8 -r3.4 f.c >f.merged.c
Alternatively, if you want to save the updates to 2.8 in the RCS file,
check them in as revision 126.96.36.199 and execute
ci -r188.8.131.52 f.c
co -r3.4 -j2.8:184.108.40.206 f.c
As another example, the following command undoes the changes
between revision 2.4 and 2.8 in your currently checked out revision
rcsmerge -r2.8 -r2.4 f.c
