I haven't read the code closely enough to know just what it does, but I
see it examines the $PATH environment variable.

(This is specific to Unix-like systems.)

If your code looks at the current directory regardless of what's in
$PATH, then it's probably misbehaving.  If the current directory isn't
specified in $PATH, the current directory shouldn't be searched.

$PATH is a list of directory paths, separated by ':' characters.  An
empty field refers to the current directory, which can also be specified
as '.'.  This can appear at the beginning (if PATH starts with ":"), at
the end (if it ends with ":", or in the middle (if it contains ":").

It's recommended *not* to include the current directory in $PATH.
