2011-03-13Fix handling of VIS_ALL: in vis(), actually encode all charactersPhilip Guenthe
as requested and give a correct estimate when they don't all fit, and in unvis() decode them instead of erroring ok nicm@, deraadt@
2010-08-24backout VIS_HEX. guenther@ points out that the C89 \xff encodingDamien Miller
idiotically accepts more then two hex digits following the \x, even on platforms where a char has 8 bits. It is therefore dangerous to have an almost-bit-not-quite compatible format in vis(3). The VIS_ALL (encode all characters) option introduced in the same commit remains.
2010-08-21Two new flags: VIS_ALL - encode all characters, not just invisible onesDamien Miller
and VIS_HEX - use C89 \xff style hexadecimal encoding. Teach unvis(3) how to deal with the hex encoding. feedback and ok millert@ chl@

2002-07-01Fix strnvis(): don't truncate unnecessarily, set the return value correctlyPaul Janzen
if we had to truncate, and don't NUL-terminate if size == 0.

we are passes an empty string. vis() and strnvis() were already OK. Based on patch by wilfried@openbsd.org
