Subject[PATCH v5 06/33] dyndbg: use ESCAPE_SPACE for cat control
Date
`cat control` currently does octal escape, so '\n' becomes "\012".
Change this to display as "\n" instead, which reads much cleaner.

:#> head -n7 /proc/dynamic_debug/control
# filename:lineno [module]function flags format
init/main.c:1179 [main]initcall_blacklist =_ "blacklisting initcall %s\n"
init/main.c:1218 [main]initcall_blacklisted =_ "initcall %s blacklisted\n"
init/main.c:1424 [main]run_init_process =_ " with arguments:\n"
init/main.c:1426 [main]run_init_process =_ " %s\n"
init/main.c:1427 [main]run_init_process =_ " with environment:\n"
init/main.c:1429 [main]run_init_process =_ " %s\n"
