True.  With the current shell syntax rules, in the following example
it is just 'somefile;' that will be colored as if it were a comment:

  grep "such #so" somefile;

But if we swap the coloring of Comments and Strings, then the whole
'#so" somefile;' would be colored as a comment, which looks ugly and
makes the command hard to read.

If you try the above example on both systems, you should be able to
see the difference.

No, no chance.  Nano is a small editor, fully parsing all the files
for which it provides syntax coloring is not within its scope.

This feature (copy-to-cutbuffer) was added in April 2006.  It is
a feature that Pico doesn't have.  There were no Ctrl+letter keys
left to assign it to, nor any function keys.  So, as it has something
to do with marked text, I suppose the idea was that a key should be
chosen that is related to toggling the mark (Ctrl+^ or Ctrl+6).
