Known bugs in the Linter bogus file options detection:

 * - Linter fails to detect multiple "upright" parameters as a bogus file option (in some cases)
 * - Conflicting border/thumb/frame options are not detected as Linter errors
 * - Capitalized versions of valid File options are usually ignored, but are not flagged as Linter bogus file options
 * - LintError bogus-image-options triggers on "Thumbtime"

In addition some other supported file options such as link3>Special:MyLanguage/Media Projects|video and multi-page formats (e.g. pdf) are also checked.

Common errors include:


 * Repeated options, e.g.  &rarr;


 * Conflicting alignment options, e.g.  &rarr;

 * Two captions, e.g.  &rarr;


 * A plain number instead of a px value, e.g.  &rarr;
