Allow for multiple occurences of "--style"

[sharkdp]

There should be a way to specify --style multiple times. This way, users can set --style=numbers,changes in their config file, but still use --style=changes on the command line.

I'd like to take this issue

Is the idea that the last argument overrides the first? So that --style=full --style=plain results in the plain style?

Exactly. It would be great if --plain and --number would also override any previous --style argument if that's possible.

@sharkdp: That sounds logical. I have created PR #371. It has code both to make style override style, and style and plain overrides each other. So only one the last one of those will have an effect.

I had to remove clap's splitting of the arguments in style. When using clap's splitting with overriding, it only keep the last one in the set. So --style numbers,changes becomes changes.
