Thank you very much Sergey Matveev. I have studied your proposed redo files for st and learned a lot. Here are my new and improved (you had a bug in default.o.do in that you forgot to depend on $src) redo files for st. Please take a look and tell me what you think.

Note that there are neither 'options' nor 'all' targets for simplicity--I don't that they are very useful. The redo command has the -x and -v options if you want more details. Also, I de-automated your automatic generation of the source (.c) and object (.o) files because it didn't work properly as you discussed in your message. If it's going to be automatic, I want it to work automatically.
