X-Git-Tag: v6.17-rc1~122^2^3~11

torture: Permit multiple space characters in kvm.sh --kconfig argument

The straightforward way of doing bash substitution for optional strings
leaves a pair of space characters, which the kvm.sh --kconfig option
rejects as ill-formed.  This commit therefore changes the corresponding
regular expression to accommodate more than one space character between
successive Kconfig options.
