Discrepancy in text and code

[epage]

#20 resolved #13 but I feel like the language is ambiguous in a way that makes me read the text as different than the code (and what was intended with #20)

clicolor says:

When set, the following rules should apply:

For me, for an environment variable to be "set" implies that its "present" but not what it is set to, which can include an empty string

no-color instead says

when present and not an empty string

This is less ambiguous and matches the example Python code.
