 Ref: #WP37807

 A translation for the following text in core was provided and approved,
 but the translation contained two placeholders instead of just one, which
 results in a PHP error.

 > Plugins extend and expand the functionality of WordPress. You may
 automatically install plugins from the <a href="%1$s">WordPress Plugin
 Directory</a> or upload a plugin in .zip format by clicking the button at
 the top of this page.

 GlotPress should:

 1. Detect translations that use a greater number of placeholders than the
 original string, and prevent the translation from being approved by
 anyone.
 2. Detect translations that use a fewer number of placeholders than the
 original string, and raise a warning to alert the translators in case of
 an error.
