Re: updmap: use tail -n 1 instead of tail -1

This is for reading config varibles from the config file. "tail -1"
is used to select the last of possibly several matches. "tail -n 1"
is not portable, unfortunately. I don't think that anybody has multiple
settings, so I'll change this into "sed q" which is portable (but selects
the first match instead).

Thanks,
