When we use `b4_` or `m4_` somewhere in the input, it is escaped as `b4@'_`/`m4@'_` so that the warning about unexpanded b4_foo/m4_foo macros does not fire. But in the case of muscles, the `@'` escape was not recognized, and an assertion was triggered. Reported by Han Zheng. <https://github.com/akimd/bison/issues/91> * src/muscle-tab.c (COMMON_DECODE): Handle `@'`. * tests/skeletons.at (Suspicious sequences): Check that case.

These two macros must be given the (main) directives so that they define a number of other macros to:

- what skeleton is used
