Hi Glenn,

      http://lists.gnu.org/archive/html/bug-texinfo/2013-08/msg00009.html
    -all-over-againly,

Basically :(.

    (For example, I have just discovered that about 1% of index entries in
    the Emacs manuals are useless because of this reason.)

They don't work as they should in Info, but humans can still get to the
right place by hand.  And they do work in TeX, HTML, etc.  Hence they
are not completely useless, hence always warning about them seems like
overkill.

    Subject: Warn about invalid index entries

Another issue is that although in Emacs you might be able to reword the
index entries and accept the resulting suboptimality, for, say, a C++
manual it would be completely infeasible.
    
    PS Maybe consider adding a --strict flag or somesuch, which will warn
    about "things that are invalid but which are normally silently
    accepted for historical reasons"...

I'm not a fan of generic options like that, but I imagine it would be
easy enough for Patrice to add an option to warn about this particular
issue, something like INDEX_SPECIAL_CHARS_WARNING to go along with the
INFO_SPECIAL_CHARS_WARNING he already did.  Patrice, wdyt?

Thanks,
K
