Fixes for Almquist Shell (ash and dash): - use local instead of typeset and make local an alias for typeset in ksh   (the name local is far more logical and is supported in dash, bash, and zsh) - use more unique variable names in addpath() and delpath() just in case   we're in a minimally POSIX compliant shell or original Bourne shell that   doesn't support local or typeset - ensure UID is set before using it to test whether to include . in PATH
