Bug 219092 – check-webkit-style should require spaces around the equal sign for Objective-C @synthesize

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Hoa Dinh]

Currently, check-webkit-style will require to have no spaces around the equal sign for "@synthesize a = b".
The codebase shows that "@synthesize a=b" is preferred.

Let's improve check-webkit-style to match what we use.

I don't have an issue with the change, but I also don't do much workin Objective-C....someone who has more experience in the area should verify this is actually what we want to do.

It looks like there are currently about 90 instances of `@synthesize foo=bar` in the WebKit stack — we should probably update these if we're changing the style rules for synthesized properties.

(...but I suppose this could be done separately)

Ideally, there should be a sentence or two below the "Reviewed by" line describing the change. Maybe something like along the lines of:

```
Teach the Objective-C style checker to prefer `@synthesize a = b` over `@synthesize a=b`. As a followup,
<webkit.org/b/219094> will enforce this style rule in existing @synthesize statements in WebKit.
```
