Changeset 31433 for branches/4.1/src/wp-includes/general-template.php

Message:

In paginate_links(), don't override custom format arguments when setting up default 'add_args'.

Since 4.1 [29780], the default value of the 'add_args' argument in
paginate_links() has been determined by parsing the current URL. This change
had the side effect of overriding custom values of 'format' that changed the
pagination query var, with the result that plugins using paginate_links()
with a custom format generated the incorrect links unless explicitly
declaring 'add_args=false' to prevent the default values from overriding. We
fix this behavior by parsing URL query vars into the 'add_args' array only
after the explicit function params have been parsed, and by skipping the
current page's pagination query var when doing this parsing (to avoid the
override).

Props obenland.
Merges [31203], [31432] to the 4.1 branch.
Fixes #30831.
