You're right.  I think we should do it basically the way you suggest,
but the saving/restoring of the environment can be done a bit more
concisely like this:

proc exec_citool {args {baseid {}}} {
    global commitinfo env

    set save_env [array get env GIT_AUTHOR_*]

    if {$baseid ne {}} {
	# as before ...
    }

    eval exec git citool $args &

    catch {array unset env GIT_AUTHOR_*}
    array set env $save_env
}

In Tcl, everything is a string. :)
