The poptBadOption() function's return is confusing if the user supplies amalgamated multiple short options, only some of which are "bad". The problem does not occur with isolated bad short options nor with bad long options. To use the popt man pages example, the short options b, c, h, n, r, s, and ? are possible, but if the user runs for instance 'parse -chnrsaw' (where 'a' and 'w' are bad short options), the error message 'parse' spits out is "-chnrsaw: unknown option" because poptBadOption() returns "-chnrsaw" (and poptStrerror() returns "unknown option" for the poptGetNextOpt() error code). poptBadOption() should return, in the case of a bad short option, a single '-' followed by the bad short option only, omitting any short options before or after the culprit. This is the expectation created by the comment in popt.h, which reads "Return the option which caused the most recent error. [...] @return offending option" (note the singular). With this simple correction, 'parse -chnrsaw' would now report "-a: unknown option", a perfectly acceptable message. Note that 'parse -c -h -n -r -s -a -w' already results in this very message.
