One problem with not designing test into the shell language
in a carefully designed way but rather growing out of program calling is that
you've got to do ridiculous things like

if [ X$oldt = X$newt ]; then

to properly handle the case of empty strings variables. (That's why
once I reach the level of testing conditionals in a script
I see if I can migrate to a different scripting language.)
