Strange show_env output when redacted variable follows empty variable

[jdx]

Discussed in #4245

I have this mise.toml file:

[settings]

[settings.status]
show_env = true

[env]
A = "a"
B = { value = "b", redact = true }

This correctly prints out the variables when cd'ing into the directory:

mise +A +B

However, if I make the variable A an empty string like this:

[env]
A = ""
B = { value = "b", redact = true }

then I get this output:

mise [redacted]+[redacted]A[redacted] [redacted]+[redacted]B[redacted]

This only happens if an empty variable if followed by a redacted variable. If I add another variable C = "c" between A and B then the output gets even stranger:

mise [reda[redacted]ted]+[reda[redacted]ted]A[reda[redacted]ted] [reda[redacted]ted]+[reda[redacted]ted]B[reda[redacted]ted] [reda[redacted]ted]+[reda[redacted]ted]C[reda[redacted]ted]

I think the issue should be obvious, but it's that the "[redaction]" string itself is being redacted
