Well, it's just a 95% kind of job (and I'm not entirely sure there
aren't a few wrong positives).  But it's a start for getting more
consistent indexing.  Testing better indexing (requiring Texinfo 6) just
now.

Description:
Remove unescaped @funindex entries

With adjacent @funindex entries of which one differs from the other
only by the absence of a preceding backslash, the one without the
preceding backslash is removed.  This is done by using the script:

    sed -i '/address@hidden/{N;s/address@hidden \\\([^\n\\]*\)address@hidden
\1$/@funindex \\\1/mg;s/address@hidden \([^\n\\]*\)address@hidden
\\\1$/@funindex \\\1/mg;P;D;}' $(git grep -l 'address@hidden')
