40381349ab fix(dmesg): detect when dmesg is truncated 
To avoid false negatives when looking for a message
in dmesg, we were previously also grepping in known
on-disk archives of dmesg (dmesg.log, kern.log).
This in turn caused false positives because we have no
guarantee that we're grepping the dmesg of the current
running kernel. Hence we now only look in the live
`dmesg`, detect if it has been truncated, and report
it to the user.

b3b7f634e6 fix(display): use text-mode compatible colors 
in text-mode 80-cols TERM=linux terminals, colors
were not displaying properly, one had to use
--no-color to be able to read some parts of the
text.

4a2d051285 minor is_cpu_vulnerable() changes (#71) 
* correct is_cpu_vulnerable() comment

As far as I can tell, the function and usage are correct for the comment
to be inverted.

Add a clarifying note as to why the value choice makes sense.

* exit on invalid varient

If this happens, it's a bug in the script. None of the calling code
checks for status 255, so don't let a scripting bug cause a false
negative.

* no need to set vulnerable CPUs

According to comment above this code:
'by default, everything is vulnerable, we work in a "whitelist" logic here.'

52a8f78885 send warning to stderr. (#53) 
With --batch json there must not be any other output on stdout, so redirect warnings to stderr will show the warning on the console and only the json output is on stdout.
