Normalize eccentric enum values

[lassik]

All enum values in options.ts seem to be spelled using lowercase-with-dashes.

Except for 2 enums:

• end_of_line values ["CRLF", "LF", "System Default"]
• indent_char values [" ", "\t"]

I would change them to be like the others, and more obvious, as follows:

• end_of_line values ["windows", "unix", "native"]
• indent_char values ["space", "tab"]

Also, I would maybe drop the native newline setting. In a multi-OS dev team, that would cause the files to be converted back and forth between Unix and Windows newlines. (Unless Git is set to do its own newline conversion back and forth, but that brings us to another issue: there's a subtle interaction between Git's and Unibeautify's newline conversion mode, which a native choice would complicate even further.) IMHO, the ideal is for the beautifier to force a particular newline encoding on all platforms. All serious programmer's text editors can handle any newline encoding on any platform.

💯% agree and I was thinking about that a few months ago.

indent_char should be deprecated: https://github.com/Unibeautify/unibeautify/blob/master/src/options.ts#L122
Replaced by indent_style: https://github.com/Unibeautify/unibeautify/blob/master/src/options.ts#L163

Cool, I didn't notice the data model supports deprecated definitions :) indent_style seems prefect, and identical to .editorconfig too.
