The last commit missed the el_GR UTF-8 Compose.pre as well as
the various ISO 8859 locales which have compose sequences
generating ‘WITH CEDILLA’ characters.

(Interestingly, some of the 8859 locales already supported
<Multi_key> <cedilla> for some CEDILLA characters, but not
for Ç or ç.)

This is further work on bug 10397.
