Details:

When converting CP1258 encoded texts to UTF-8, the last character may be
dropped, without any error indication.  This appears to happen regardless of
the length of the input text.  Conversion from CP1252 works as expected.

The attached program iconv-bug.c shows that; the last assertion fails.

Apparently, the last character is considered to be a combining character, so
cp1258_mbtowc() returns RET_TOOFEW(1), but unicode_loop_convert() then returns
without calling cp1258_mbtowc() again.
