Enforce the amount of whitespace surrounding keywords.

Given the following tab-indented source code:

function foo() {
	if (true) {
		try {
			bar();
		}
		catch (err)
		{
			baz();
		}
	}
}

Using brace-style to use "1tbs", we end up with tabs around the catch keyword.

function foo() {
	if (true) {
		try {
			bar();
		}		catch (err)		{
			baz();
		}
	}
}

It doesn’t seem possible to fix this with the existing eslint rules:

• keyword-spacing only asserts that there’s a non-zero amount of whitespace around keywords
• no-multi-spaces ignore tabs
• no-tabs isn’t useful because we’re using tabs for indentation too

Possible solutions:

• add an option to keyword-spacing to enforce exactly one space (my suggestion)
• add an option to no-tabs to only flag tabs that aren’t at the beginning of the line (suggested by @platinumazure)
• generalise no-multi-spaces to work for arbitrary whitespace, not just spaces

Tested on eslint 3.10.2.
