Error: ⚠ Missing filename on 5.2.0

[xfzv]

On 5.1.0 and older, I could run e.g.

% watch -c -n 5 -t "sudo emlop p | tspin"
% journalctl -b -f -n 50 -u ssh | tspin

After updating to 5.2.0:

% tspin --version
tspin 5.2.0

these commands now give the following error instead:

Error:   ⚠ Missing filename (tspin --help for help)

tailspin/src/config/mod.rs

Line 47 in 2eafd02

#[error("Missing filename ({} for help)", "tspin --help".magenta())]

This still works fine:

% tail -f /path/to/file.ext | tspin

Not sure if this is a bug.

Thanks.

Solved with 5.2.1. - #210
