dir: store EXC_FLAG_* values in unsigned integers

Browse Source 
The values defined by the macro EXC_FLAG_* (1, 4, 8, 16) are stored
in fields of the structs "pattern" and "exclude", some functions
arguments and a local variable.  None of these uses its most
significant bit in any special way and there is no good reason to
use a signed integer for them.

And while we're at it, document "flags" of "exclude" to explicitly
state the values it's supposed to take on.
