Add symbol to mark NUL handling in each tool (and where it is missing)
The assumption of NUL-terminated strings is actually quite a good one in
least cases. You don't have to worry about paths, because they may not
contain NUL.
Same applies to arguments passed to you. Unless you have to unescape,
there is no way for you to receive a NUL.
There are two important exceptions though, and it's important that we
address them, or else we get unexpected behaviour:
1) All tools using unescape() have to be strict about delimlen.
Else they end up for instance unescaping
'\\0abc'
to
'\0abc',
which in Java 7's string-vision is an empty string.
2) All tools doing line wrenching and putting them out
again as lines again.
puts() will cut each line containing NULs off at the first
occurence.
