--blank-lines-after-declarations
The '-bad' option forces a blank line after every block of
declarations. The '-nbad' option does not add any such blank
lines.
For example, given the input
char *foo;
char *bar;
/* This separates blocks of declarations. */
int baz;
indent -bad
produces
char *foo;
char *bar;
/* This separates blocks of declarations. */
int baz;
and indent -nbad
produces
char *foo;
char *bar;
/* This separates blocks of declarations. */
int baz;
