this file makes me cry. there is so much shit going on here.

Since a8dba452 the search index didn't
properly index numeric words anymore, instead they were added as new
words to the word list each time they were indexed, leading to an
ever-increasing index size.

changes made to 9e8bcd5f.

I accidentally hit the wrong button on github :-) This translation added

Bi-directionality is generally a huge pain in the arm, browser vendors
only added a few improvements quite recently. This fix only works in
Mozilla and Webkit currently. Affected syntax was links and media and all
opening and closing syntax (e.g. code and del and various plugin syntax).

headers in the additional headers. The To-header in the additional
headers prevented mail sending on some systems.

Prevent table entry syntax swallowing multiple preceeding blank lines
(a) this shouldn't be necessary, blank lines are handled by paragraph
    processing
(b) avoids issues with greedy table syntax competing with plugins
