[PATCH] DEL char (ASCII 127 decimal) now escaped

[Josh Lehan]

Hello!

While testing, I noticed that printf_encode() makes
control characters human-readable, with one exemption,
the DEL character (ASCII 127).

Assuming this exemption was unintentional, here is a trivial patch
to make it appear as an escaped \x7f instead of a literal
DEL character in the output.

I am trying to allow the choice of wireless network name and password
to be as binary-clean as possible, and this will help.

Thank you!
