Correct formatting for special characters

[pop]

Things like this:

script: "date +%M"

should be displayed as

script: "date +%M"

but instead they're displayed as a golang Printf error:

script: "date +<%M MISSING VARIABLE>"

(not verbatim, just like that)

This should be a simple fix. I have a partial patch ready, just not sure the best way to test it.
