* Fix a couple of imprecisions in the file/ docs The `+` flag to `(file/open)` was incorrectly documented as being for appending. Instead, this allows to read to files opened with `:w` or `:a`, and to write to files opened with `:r`. This is the same as the `+` flag in `fopen(3)`. The `(file/seek)` function was documented as having both `whence` and `n` as optional arguments. It also didn't say what the default for `n` was. Anyway, this doesn't make sense, as a default of `:cur` and `0` would effectively make `(file/seek f)` a no-op. I also amended a test so both `(file/seek f :set 0)` and `(file/seek f :set)` are covered and checked to move to the beginning of the file. * Remove useless check for argc >= 2 We already determined it is between 2 and 3 with `janet_arity(argc, 2, 3)`. * Dump args in assertion * Unroll loop in test * Differentiate failure messages
