+Subject: [PATCH] subreader: fix out of bound write access when parsing .srt
+
+This broke .srt subtitles on gcc-4.8. The breakage was relatively
+subtle: it set all hour components to 0, while everything else was
+parsed successfully.
+
+But the problem is really that sscanf wrote 1 byte past the sep
+variable (or more, for invalid/specially prepared input). The %[..]
+format specifier is unbounded. Fix that by letting sscanf drop the
+parsed contents with "*", and also make it skip only one input
+character by adding "1" (=> "%*1[...").
+
+The out of bound write could easily lead to security issues.
+
+Also, this change makes .srt subtitle parsing slightly more strict.
+Strictly speaking this is an unrelated change, but do it anyway. It's
+more correct.
