[RFC] unneeded extra brace in infrun.c (handle_inferior_event)

I can do the following, all within a short period:
  - remove the braces (without indentation change)
  - commit
  - run gdb_indent.sh
  - commit
  
That way, we have one commit which contains a code change, but the diff
is readable. The second diff may be unreadable, but will contain no code
change.

Should I go ahead?
