Transliterate latin small letter e with acute (u+00e9) to "e" in "C" locale

[Jack Bates]

In en_US.UTF-8 locale, transliterating latin small letter e with acute
(u+00e9) to ascii yields "e", however in "C" locale, it yields "?"

  $ echo -e "\xc3\xa9" | LC_ALL=C iconv -f utf-8 -t ascii//TRANSLIT
  ?
  $ 

I think it's desirable to yield "e" in "C" locale, as in en_US.UTF-8
locale - am I correct? or is latin small letter e with acute
deliberately omitted from C-translit.h.in?

Would a patch to add latin small letter e with acute to C-translit.h.in
be welcome?

Thanks for maintaining glibc!
