Subject: CODING_STYLE: explicitly allow braceless 'else if'
X-Git-Tag: TizenStudio_2.0_p2.3~2536^2~70
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b11887ad40df40dada4bf70b9c6702de386a8a87;p=sdk%2Femulator%2Fqemu.git

CODING_STYLE: explicitly allow braceless 'else if'

It's already allowed by the example; there are about 1800 instances in the
tree; and disallowing it would lead to

    if (a) {
        ...
    } else {
        if (b) {
            ...
        } else {
            if (c) {
                ...
            } else {
                if (d) {
                    ...
                } else {
                    ...
                }
            }
        }
    }

instead of

    if (a) {
        ...
    } else if (b) {
        ...
    } else if (c) {
        ...
    } else if (d) {
        ...
    } else {
        ...
    }

which is more readable.

 An exception is the opening brace for a function; for reasons of tradition
 and clarity it comes on a line by itself:
