The documentation for [[ says this about the == and != operators,
which take patterns as the right-hand side:
Any part of the pattern may be quoted to force it to
be matched as a string.
It seems reasonable that quoting any part of the rhs to the =~
operator should cause it to behave in the same manner.
Since the arguments to [[ don't undergo any of the expansions that
require quoting to protect them, there's no reason for =~ to act
differently than the other operators that do pattern matching.
