This is from lib/database.cc:

const char *
_find_prefix (const char *name)
{
    unsigned int i;

    for (i = 0; i < ARRAY_SIZE (BOOLEAN_PREFIX_INTERNAL); i++) {
	if (strcmp (name, BOOLEAN_PREFIX_INTERNAL[i].name) == 0)
	    return BOOLEAN_PREFIX_INTERNAL[i].prefix;
    }

    for (i = 0; i < ARRAY_SIZE (BOOLEAN_PREFIX_EXTERNAL); i++) {
	if (strcmp (name, BOOLEAN_PREFIX_EXTERNAL[i].name) == 0)
	    return BOOLEAN_PREFIX_EXTERNAL[i].prefix;
    }

    for (i = 0; i < ARRAY_SIZE (PROBABILISTIC_PREFIX); i++) {
	if (strcmp (name, PROBABILISTIC_PREFIX[i].name) == 0)
	    return PROBABILISTIC_PREFIX[i].prefix;
    }

    INTERNAL_ERROR ("No prefix exists for '%s'\n", name);

    return "";
}

I set ":set list" and ":set listchars=tab:>-" to visualize tabs in vim. This shows me
* the first two codelines (leaving out empty lines) are indented by 4 spaces
* the first line in the first for loop is indented by only one TAB (IMHO should be
  two, because it is one leven down): this is a pattern you can find throughout the
  codebase.
* the next two lines are indented by four spaces
* the first line of the second for-loop is indented by one TAB.
* and so on...

Am I misinterpreting something here? Is this intended to be done that way?
I also get confused by the different lengths of TAB/space-indenting. But probably
that's because I never used it...
