[PATCH] Do not fail test if '.' is part of $PATH

From: H.Merijn Brand <h.m.brand@xs4all.nl>

Message-ID: <20181201180757.0b2d3c89@pc09.procura.nl>

When $PATH contains the current directory as .:PATH, PATH:., PATH:.:PATH, or (maybe worse) as :PATH, PATH:, or PATH::PATH - as an empty entry is identical to having dot in $PATH - this test used to fail

This patch was tested with PATH=$PATH, PATH=.:$PATH, PATH=$PATH:., PATH=$PATH:.:/bin, PATH=:$PATH, PATH=$PATH:, and PATH=$PATH::/bin
