* Add --null option (sort #defines here)
* Add process_lines function to util.c that reads newline-terminated
or null-terminated lines (with self-sizing buffers, etc) and iteratively
invokes a provided function. Use this to dramatically simplify:
-T handling for -c, --exclude-from-file, and --include-from-file.
* Add -T handling to -x (via include_from_file)
Hopefully, this will fix the openoffice port and a couple of
others that rely on -T and --null.
directory, then a file with that symlink as a prefix can drop a file
outside of the current directory, which can be a security hole.
Plug this hole by refusing to extract files if a prefix of the
pathname is a symlink. The -P option disables this check.
table for the hardlink cache. This dramatically improves
performance when archiving millions of hardlinked files.
While I'm here, clean up some style bugs (per Bruce Evans)
and clarify some comments.
