lib/libedit : chartype.h read.c
regress/lib/libedit/read: Makefile
Log message:
Fix the CHARSET_IS_UTF8 case in read_char().
For now, this mainly help programs explicitly using
wide-character functions like el_wgetc(3) and el_wgets(3).
1. After reading an invalid byte sequence, do not throw away additional
valid bytes; fix by me using mbrtowc(3), obsoleting utf8_islead().
2. When read(2) returns EOF, return that information to the caller,
do not prod on and potentially access garbage data in the buffer;
from Linas Vepstas via NetBSD read.c rev. 1.70 2013/05/27.
3. After read__fixio() failure, restore errno to the one set by read();
from Steffen Nurpmeso via NetBSD read.c rev. 1.68 2012/09/10.
4. After read__fixio() success, restore errno to the initial state
upon function entry; fix by me.
OK czarkoff@. Also committed to NetBSD.
