Open to debate.  I'd think it's not very dangerous at the *end* of the PATH.
The usual worry is a Trojan masquerading as a normal utility, chosen
early because of the order of things in the searchpath.  When I use ".", I
put it at the end.  It's no worse than the fairly common ~/bin in a
searchpath,
which I'd actually rate more dangerous --
   1) It's just as hard/easy to put something in ~/bin as in ~/
   2) It's more likely to go unnoticed in ~/bin

And, since I do lots of development of itsy-bitsy scripts and C programs,
I'm using such stuff all the time.


Nevertheless it should not be removing the entry unless its a dup. I
