In my releases logname variable is completely missing. Also the LOGNAME
parameter is writable. Zsh use the logname variable only to store the value of
the LOGNAME special parameter. I already posted patches for that but it seems
that Richard does not like my patches too much. Here is a patch against
beta9. It makes HOSTTYPE, OSTYPE, MACHTYPE, VENDOR, ZSH_VERSION, LOGNAME and
USERNAME non-special parameters. They will behave exactly as before, except
that they are writable, these name can be used as local parameters etc. This
increases flexibility and simplifies the code.
