 A few simple changes to the `// Paging` block in wp-includes/query.php

 * `$page` is being checked with `empty()`, but is already passed through
 `absint()` which can only return an integer. Just using `!` makes it a bit
 less confusing.

 * `$pgstrt = '';` is redundant as it's overwritten on the following line

 * `$limits = 'LIMIT ' . $pgstrt . $q['posts_per_page'];` is repeated, so
 moved outside the if/else block for readability.
