+Subject: [PATCH] oggenc: Don't assume the output path ends in a file name.
+
+Origin: https://gitlab.xiph.org/xiph/vorbis-tools/-/merge_requests/7
+
+oggenc attempts to create any specified directories in the output
+file path if they don't exist. The parser was assuming there was
+a final filename after the last directory separator, and so would
+try to read off the end of the argument if it was a bare directory
+such as `./` or `outdir/`. This adds a check to make sure the
+scan isn't starting off the end of the path string.
+
+Thanks to Frank-Z7 (Zeng Yunxiang) at Huazhong University of Science
+and Technology (cse.hust.edu.cn) for the report.
