[tldoc] Changes to KPS table

[Karl Berry]

    I'd suggest correcting slightly 'Kpathsea file types' table
    Below diff against the current English sources as on p4 depot

Ok, thanks.

I hate that table, I'd like to delete it next year.  It seems silly to
include it, does anyone really look at all that junk?  Seems like anyone
who is interested would be running tools or looking at the code.
(Or at least we should auto-update it somehow.)
