This may also not be an issue any longer, but (many) years ago I learned
(probably from Larry Wall) to avoid using 'test -n ...' when possible,
as it was too often *not* a shell builtin and therefore was a
performance hog as a subshell was spawned.  I routinely use 'case'
statements instead of any tests for (non-)empty strings.
