redo depending on markdown, etc.

[The-Blue-Wizard]

I attempted to build a redo on my Devuan Linux box, and upon invoking "./redo" at the shell, I get the following messages:

redo all
redo _all
redo redo-sh

Nothing much to do. Try 'redo t/all' or 'redo test'

I think there are several assumptions that redo makes, but I am not sure. Also, I am not sure which markdown library redo is using. Care to take a look?
