Comment (by birgire):

 @mdgl that's interesting.

 To handle a comma sepereated list of mime types, like

 {{{
 application/x-pdf, application/pdf
 }}}

 I think it would be logical to extend {{{sanitize_mime_type}}} to support
 this.

 For example by adding a single comma (,) into the {{{preg_replace}}} part
 of that function.

 So instead of this line of the {{{sanitize_mime_type()}}} function:

 {{{
 $sani_mime_type = preg_replace( '/[^-+*.a-zA-Z0-9\/]/', '', $mime_type );
 }}}

 we could instead use this:

 {{{
 $sani_mime_type = preg_replace( '/[^-+*.,a-zA-Z0-9\/]/', '', $mime_type );
 }}}
