New features:

• -acl finds files with non-trivial Access Control Lists (from FreeBSD)
• -capable finds files with capabilities set
• -D all turns on all debugging flags at once

Fixes:

• LS_COLORS handling has been improved:
  • Extension colors are now case-insensitive like GNU ls
  • or (orphan) and mi (missing) files are now treated differently
  • Default colors can be unset with di=00 or similar
  • Specific colors fall back to more general colors when unspecified in more places
  • LS_COLORS no longer needs a trailing colon
• -ls/-fls now prints the major/minor numbers for device nodes
• -exec ; is rejected rather than segfaulting
• bfs now builds on old Linux versions that require -lrt for POSIX timers
• For files whose access/change/modification times can't be read, bfs no longer fails unless those times are needed for tests
• The testsuite is now more correct and portable
