cursor handling with utf8 support
the code relative to the cursors movements now respects the width of the characters (zero, one or two cells).
fix compilation on glibc
glibc needs _GNU_SOURCE defined to make IOV_MAX visible. Use AC_USE_SYSTEM_EXTENSIONS and make sure to include compat.h before everything else. Found by cage_, thanks!
change default quote continuation prefix
using "> " as prefix for both first and continuation lines was a bit ambiguous.
fix a case of use-after-free in parser_set_buf
p->buf and buf almost always overlap. This means that once we free(p->buf), buf becomes invalid. It probably never crashed on memcpy since because the buffer is almost always quite small.
fixed strtonum prototype
found by cage_: thanks!
