+# If you use complex aliases of form '!f() { ... }; f', you can use the null
+# command ':' as the first command in the function body to declare the desired
+# completion style.  For example '!f() { : git commit ; ... }; f' will
+# tell the completion to use commit completion.  This also works with aliases
+# of form "!sh -c '...'".  For example, "!sh -c ': git commit ; ... '".
