Twenty Sixteen: Replace inline control structure in twentysixteen_content_image_sizes_attr()

[SergeyBiryukov]

Background: #38384 for Twenty Seventeen.

See ​twentysixteen_content_image_sizes_attr().

To improve code readability, lines 374, 377, 379, and 380 should be changed to a proper if ( ) {} block.

Development of Twenty Sixteen happens on GitHub. This should be reported at ​https://github.com/WordPress/twentysixteen/issues.

Replying to ocean90:

Development of Twenty Sixteen happens on GitHub. This should be reported at ​https://github.com/WordPress/twentysixteen/issues.

Should we close #38338 and #38623 with the same reasoning?

It's counter-intuitive that all bundled themes (including Twenty Seventeen) are developed here, while Twenty Sixteen is developed elsewhere.

@davidakennedy Should I reopen the ticket or file it on GitHub? :)

[SergeyBiryukov]

Reopening, as there's a consensus on merging Twenty Sixteen into core SVN in #36497.

In this changeset: https://core.trac.wordpress.org/changeset/41343
I think should be a space before { in line 374 if ( 840 <= $width ){
