Macros seem really hacky, but my goal was to just declare the format strings that println!() uses in one place.

I don't have enough understanding of Rust's string comparison to compare val to a string, so I made a throwaway Option to compare to.

He @brewingcode! I'm not the repo person here, but I thought I might help you here. I don't think you need the temporary x here, you can straight up compare val == Some("full").
You might even be able to make something like
let width = match matches.value_of("width") {
Some("full") => return terminal width,
Some(val) => parse the thing,
None => 80,
}
This is so we can start modifying the width of the filename field (at index 0) based on a user-supplied width.
Use the terminal_size crate to use the full terminal width.

As noted in #39, filenames quickly run into truncation issues. This PR allows you to change the output width from the default of 80 chars to another value. Additionally, specifying
fullinstead of a number will use theterminal_sizecrate to use the whole width of the terminal.
