I went with the existing patch, but gave a little more thought to
string_escape_mem. Stuff that bugs me:
- ESCAPE_NP sounds like it means "escape nonprinting
characters", but actually means "do not escape printing
characters"
- the use of the "only" string to limit the list of escaped
characters rather than supplement them is confusing and kind
of unhelpful.
- most of the flags are actually totally unused
So what I'd like to do is:
- eliminate unused flags
- use the "only" string to add to, rather than replace, the list
of characters to escape
- separate flags into those that select which characters to
escape, and those that choose the format of the escaping ("\ "
vs "\x20" vs "\040".)
I've got some patches that do all that and I think it works. I need to
clean them up a bit and fix up the tests.
