queue_pop() still aborts for a 4095-byte pathname: after copying its final
byte, ++j is 4095, which satisfies BUFFER_SIZE - 1. Use PATH_MAX for popped
and compare j against PATH_MAX so every pathname that fits dent_path also
fits the queue buffer.

Verdict - Needs revision

Pre-existing issue:

read_all.c:218 has an unnecessary blank line before a closing brace, as
reported by make check.
