Thanks.
Pushed with two changes:
- corrected spelling of your name in the commit log;
- make the test print saved stderr if it was not a stack overflow

I also pushed this:

    build: avoid build failure with --enable-gcc-warnings
    * src/kwset.c (bmexec_trans): Define with _GL_ATTRIBUTE_PURE,
    per suggestion from recent gcc snapshot.
