Mostly fixed in trunk revision 115303.

The only remaining problem is with MULE-is13194.map, in which the
modified code generates an empty equivalence list.  But a similar
problem happens with list-charset-chars, so I guess this charset needs
some special handling (it seems to be mapped to a private plane, see
ind-util.el).

Perhaps Handa-san (CC'ed) could help us out here.

Btw, while removing these and similar files from the repository,
please keep in mind the possibility that Emacs is bootstrapped in a
non-ASCII directory, which could use characters from these charsets.
Let's not remove any files that will defeat such a possibility.
