check_oracle in the 1.4.15 release doesn't correctly parse the output gotten from at least Oracle 11 (with german locales). I guess it's probably more. Also it completely needlessly uses sed where basic bash string parsing actually does more than suffice (and does not run into possible problems with locales like sed ;)). -- Just turning attached patch of github issue #1015 into a push request. (Closes #1015 and #1191)
