Add leading "0:" to output involving sub-minute times?

[flexibeast]

Firstly, thanks for emlop!

This just a small thing: i find times like a bare "45" for "45 seconds" to be disorienting, as from other contexts i'm used to sub-minute times being represented as e.g. "0:45" or "0:0:45". (And in those contexts, a bare "45" is used to mean "45 minutes" or "45 hours".)

Might you be willing to change the output format accordingly, or make this an option? (Unless this option already available, and i've missed it ....)

Thanks for suggestion. I prefer the shorter format, but this is subjective and it's easy to add another format (there's already an option to display durations as seconds).

Would you like to try writing a PR for this ? It's an easy one, even if you never wrote any Rust before. There are 3 steps:

• Add a possible_value to the duration arg in cli.rs
• Add the corresponding branch to the DurationStyle enum, DurationStyle.from_str fn, and fmt_duration fn in main.rs
• Add cases to the duration unittest in main.rs

Thanks for being open to this! Sure, happy to try to put together a PR. :-)

i've cloned the repo, and tried running cargo test, but two tests failed:

failures:

---- commands::tests::timespan_next_ stdout ----
thread 'commands::tests::timespan_next_' panicked at 'assertion failed: `(left == right)`
  left: `2020-01-01T00:00:00+00:00`,
 right: `2019-12-31T13:00:00Z`: year 2019-01-01T00:00:00+00:00', src/commands.rs:852:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

---- proces::tests::start_time stdout ----
thread 'proces::tests::start_time' panicked at 'Couldn't parse   PID                  STARTED', src/proces.rs:130:29

Is this something that should be addressed before proceeding further? Would you like the backtrace?

[vincentdephily]

I've extracted those test failures into their own issues, let's handle them individually. Bugfixes are more important than new features, but feel free to focus on the issues that interest you.

All tests now passing, thanks! Will start working on the PR. :-)
