A couple reasons for this: * the docopt crate is "unlikely to see significant future evolution", and the wider docopt project is "mostly unmaintained at this point". clap/structopt is more full-featured, has more natural subcommand support, etc. * it may allow me to shrink the binary (#70). This change alone seems to be a slight regression, but it's a step toward getting rid of regex, which is pretty large. And I feel less ridiculous now that I don't have two parsing crates anyway; prettydiff was pulling in structopt. There are some behavior changes here: * misc --help output changes and such as you'd expect from switching argument-parsing libraries * I properly used PathBuf and OsString for stuff that theoretically could be non-UTF-8. I haven't tested that it actually made any difference. I'm also still storing the sample file dirname as "text" in the database to avoid causing a diff when not doing a schema change.
