+### Please describe the problem.
+
+spotted that in my script I have "incorrectly" passed both -c and its value within the same single argument ('-c annex....'). But surprisingly annex neither treated it correctly, nor complained that something was incorrectly passed in. Shouldn't it fail if option is not '-c' but '-c smthelse' or correctly treat the value in such as case?
+
+### What version of git-annex are you using? On what operating system?
