That's probably correct, it reflects the "sh-like aspects"
of code (as I said, csh is a terrible scripting shell, and
this is also true regarding its configuration files). So
those entries look correct.
I'm not a zsh user, so I can't say this for sure. I'm heavily
infected with csh already. ;-)

The reason might be that the history, at this point in time,
did only contain 10 entries. I don't know how the content
of ~/.zhistory behaves if more than one shell is running
for a given user...
The Z shell is very customizable and can automate routine
tasks (regarding the shell dialog) in a pleasant manner.
If you want the last 10 commands to be displayed before the
shell prompt appears, try something like this in ~/.zshrc:
function precmd {
history 10 | awk 'BEGIN {histcmds=10} { printf("\t%2d\t%s\n", -(histcmds-i), $0); i++ }' | grep -v "histcmds"
}
Not tested, but it seems to be much easier as zsh simply
defines a function "precmd" and doesn't require the user
to fight with quotes, doublequotes and escaping as csh
successfully does. :-)
