[ To directly answer your question;  No ]

I believe that you're doing your best to make your system vulnerable to a
trojan horse attack with a brain-damaged path like this.  

  *** DOT SHOULD NEVER BE FIRST IN YOUR PATH. ***

There are security papers galore that try to beat this into people, but they
just don't listen.  It IS a very good idea though.

Also, it could be argued that general users should not have /etc in their
paths...

If you MUST have dot (.) in your path, then at least put it at the very end.

(ie: set path = (~ ~/bin $lpath /usr/local/bin /usr/ucb /usr/bin /usr/etc .)

If you don't know why dot is bad in front of your path,  send me email telling
me why you need to know. :-)
