branches:  trunk

description:
lint: add quotes around placeholder in message about undefined variable

Before: error: expected undefined [99]
After:  error: 'expected' undefined [99]

Seen in external/mpl/bind, which for Clang defines in stdatomic.h:
> #define atomic_exchange_explicit(obj, desired, order) \
>     __c11_atomic_exchange_explicit(obj, expected, order)
Note the mismatch between 'desired' and 'expected'.
