/// Macro for printing to the trace output, without a newline.

/// Equivalent to the `trace_println!` macro expect that a newline is not
/// printed at the end of the message.

/// # Examples
///
/// ``` no_run
/// trace_print!("this ")
/// trace_print!("will ")
/// trace_print!("be ")
/// trace_print!("on ")
/// trace_print!("the ")
/// trace_print!("same ")
/// trace_print!("line ")
/// print!("this string has a newline, why not choose println! instead?\n");
