<pre>Take the following program where an unknown Doxygen command is used:
/**
* \unknown unknowns
*/
int main() {}
Compiling with clang r201876 and only -Wdocumentation-unknown-command results
in no warning at all. It is necessary to compile with both
-Wdocumentation-unknown-command -Wdocumentation to get the expected warning:
% ~/LLVM/build/Release+Asserts/bin/clang++ -Wdocumentation-unknown-command
-Wdocumentation clang.cpp
clang.cpp:2:4: warning: unknown command tag name
[-Wdocumentation-unknown-command]
* \unknown Unknown.
^
1 warning generated.
While it can be expected that users who use -Wdocumentation-unknown-command
will also use -Wdocumentation, this behavior is still surprising.</pre>
