I still think this should be a defcustom instead with a setter function
that checks for the actual availablity of array variables.  The user
should have the opportunity to not use arrays at all even when the shell
supports it.  Using array variable syntax to get the major version
number of the installled Bash might not work in those shells that don't
have arrays.  I can't test an old Bash, but dash doesn't recognize the
syntax at all.  There should be no fallback to checking just the version
of bash since array variables may have been backported or disabled for
the actual variant of Bash that is used.  Also, the code as presented
doesn't deal with the possibility that Tramp might be invoking a
different shell on a remote machine, but that is a problem in more areas.
