Fix a bug when converting strings with 1 character using TCVN5712-1
It isn't necessary to buffer the last character of strings. This can cause a bug with strings that have 1 character between 0x0041 and 0x01b0. [BZ #13691] * iconvdata/tcvn5712-1.c (FROM_LOOP): Fix a bug when converting strings with only 1 character between 0x0041 and 0x01b0. * wcsmbs/Makefile (tests): Add tst-mbsnrtowcs. * wcsmbs/tst-mbsnrtowcs.c: New file.
