diff --brief no longer mistakenly reports diff. with 0-sized /proc/ files
Normally, it is safe to assume two regular files are different when
their st_size values are different. However, that assumption may
be invalid if either value is zero, as happens with files on Linux
/proc and /sys file systems. Since skipping this optimization will
usually cost very little (one read syscall, to read zero bytes),
it is fine to accommodate those unusual files.
* src/analyze.c (diff_2_files): Do not assume regular files differ
just because their st_size values differ when one or more is 0.
* src/diff.c (compare_files): Likewise.
* tests/brief-vs-proc-stat-zero: New test.
* tests/Makefile.am: Add it.
* NEWS (Bug fixes): Describe it.
