Spaces in rustic-rustfmt-args string are not divided into separate arguments

[nickbp]

As a workaround for rustfmt's insistence on ignoring the Cargo.toml edition that everything else honors, I've settled on just passing it --edition 2021 all the time, much more preferable than leaving rustfmt.toml files scattered everywhere.

However, I found that the rustic-rustfmt-args setting doesn't work with spaces. Specifically, I noticed is that this works:

(setq rustic-rustfmt-args "--edition=2021")

But this doesn't:

(setq rustic-rustfmt-args "--edition 2021")

The latter version results in the following error in a *rustfmt* buffer:

Unrecognized option: 'edition 2021'

This error can be duplicated by hand in a manual rustfmt invocation at the commandline:

$ rustfmt "--edition 2021" example.rs 
Unrecognized option: 'edition 2021'

My assumption is that multi-word rustic-rustfmt-args aren't being broken down into separate arguments. Per above, the workaround for a single argument is to avoid spaces by using the --x=y format. However this may not be an option for someone that has multiple separate arguments that they'd like to pass (like say --color=never --edition=2021?).

Thanks for the bug report. Should be a simple fix.

Should be working now.
