How many manuals set documentlanguage?  With the proliferation of
documentencoding set to UTF-8, I think disabling the collation for
"en" will be next to futile.

How come format_printindex takes such a large proportion of the
processing?  Isn't that strange?  Index entries are usually a small
proportion of the overall manual's text, so processing the manual
should take the lion's share.  The index in the manual you were timing
has about 8K entries, but the entire manual is 100K lines, so the
index is less than 10% of the total volume.  How come its processing
is so expensive?
