grepc: Fix glitch with incorrectly indented code

Avoid this glich from glibc:

./sysdeps/unix/sysv/linux/x86/sys/ucontext.h:133:
typedef struct
  {
    gregset_t __ctx(gregs);
    /* Note that fpregs is a pointer.  */
    fpregset_t __ctx(fpregs);
    __extension__ unsigned long long __reserved1 [8];
} mcontext_t;

/* Userlevel context.  */
typedef struct ucontext_t
  {
    unsigned long int __ctx(uc_flags);
    struct ucontext_t *uc_link;
    stack_t uc_stack;
    mcontext_t uc_mcontext;
    sigset_t uc_sigmask;
    struct _libc_fpstate __fpregs_mem;
    __extension__ unsigned long long int __ssp[4];
  } ucontext_t;
