Description

macchina --bar shows an extra whitespace at the end of the battery bar before the closing bracket.

Reproducible

Yes

Reason

/// Return the correct amount of colored blocks: colored blocks are used blocks
pub fn colored_blocks(elems: &Elements, block_count: usize) -> ColoredString {
    let colored_blocks = elems.format.bar_glyph.repeat(block_count);
    colored_blocks
        .chars()
        .collect::<Vec<char>>()
        .chunks(1)
        .map(|c| c.iter().collect::<String>())
        .collect::<Vec<String>>()
        .join(" ")
        .color(elems.format.color)
}

This function is meant to split up the amount of blocks into chunks, add a space between them, color and return them. but, whenever the block_count is equal to 10, it adds an extra space!
