[Tcsh] How is merge in savehist supposed to work?

[Dr. Werner Fink]

Hi

after a report of a user I've done a small test case to show the
problem:

 boole:~ # useradd -m -s /bin/tcsh c1
 boole:~ # vi /home/c1/.tcshrc
 boole:~ # cat /home/c1/.tcshrc
 set histdup=prev
 set history=8
 set savehist=($history merge lock)
 boole:~ # su - c1
 boole /home/c1> touch m1
 boole /home/c1> touch m2
 boole /home/c1> touch m3
 boole /home/c1> touch m4
 boole /home/c1> touch m5
 boole /home/c1> touch m6
 boole /home/c1> touch m7
 boole /home/c1> touch m8
 boole /home/c1> logout
 boole:~ # su - c1
 boole /home/c1> cat m1
 boole /home/c1> cat m2
 boole /home/c1> cat m3
 boole /home/c1> cat m4
 boole /home/c1> cat m5
 boole /home/c1> cat m6
 boole /home/c1> cat m7
 boole /home/c1> cat m8
 boole /home/c1> logout
 boole:~ # cat /home/c1/.history 
 boole:~ # cat /home/c1/.history 
 #+1689237920
 touch m1
 #+1689237921
 touch m2
 #+1689237922
 touch m3
 #+1689237923
 touch m4
 #+1689237924
 touch m5
 #+1689237925
 touch m6
 #+1689237926
 touch m7
 #+1689237927
 touch m8

... looks like `merge` does not work to get the recent history
