Don't warn when we have no implementation of this function (since it's on-by-default); reformat the changes entry; fix an overlong line.

o Minor features:
|
|
- If set to 1, Tor will attempt to prevent basic debugging
|
|
attachment attempts by other processes. It has no impact for
|
|
users who wish to attach if they have CAP_SYS_PTRACE or if they
|
|
are root. We believe that this feature works on modern
|
|
Gnu/Linux distributions, and that it may also work on OSX and
|
|
some *BSD systems (untested). Some modern Gnu/Linux systems
|
|
such as Ubuntu have the kernel.yama.ptrace_scope sysctl and by
|
|
default enable it as an attempt to limit the PTRACE scope for
|
|
all user processes by default. This feature will attempt to
|
|
limit the PTRACE scope for Tor specifically - it will not
|
|
attempt to alter the system wide ptrace scope as it may not even
|
|
exist. If you wish to attach to Tor with a debugger such as gdb
|
|
or strace you will want to set this to 0 for the duration of
|
|
your debugging. Normal users should leave it on. (Default: 1)
