annotate lib/argp-help.c @ 14379:2330aac2ae54

maint: adjust cpp indentation to reflect nesting depth I.e., in a block of code that begins with an unnested "#if", put one space between the "#" in column 1 and following token. For example, -#include <sys/vfs.h> +# include <sys/vfs.h> Do this only in .c files that are part of a module I maintain. * lib/linkat.c: Filter through cppi. * lib/nanosleep.c: Likewise. * lib/openat.c: Likewise. * lib/openat-die.c: Likewise. * lib/dup3.c: Likewise. * lib/fchownat.c: Likewise. * lib/flock.c: Likewise. * lib/fsync.c: Likewise. * lib/fts.c: Likewise. * lib/getpass.c: Likewise. * lib/gettimeofday.c: Likewise. * lib/userspec.c: Likewise. * Makefile (sc_cpp_indent_check): New rule, to check this.
