+Subject: [PATCH 11/17] patch 9.2.0663: [security]: runtime(netrw): code
+ injection in local file deletion
+
+Problem:  [security]: s:NetrwLocalRmFile() escapes only the backslash in
+          the file name before passing it to :execute, so a name
+          containing "|" injects arbitrary Ex commands when the file is
+          deleted (cipher-creator)
+Solution: Use fnameescape() to correctly escape the file name
+          (Yasuhiro Matsumoto).
