Browse Source 
The --verbatim-files-from option disables option handling in
file lists.  The --no-verbatim-files-from reverts its effect.

The --null option implies --verbatim-files-from.  This restores
the documented behavior, broken by 26538c9b.

* src/names.c (name_elt): New member: file.verbatim
(name_add_file): Take 'verbatim' state as its third parameter.

is set.
* src/tar.c: New options --verbatim-files-from and
--no-verbatim-files-from.

* doc/tar.texi: Document --verbatim-files-from and
--no-verbatim-files-from options.
* NEWS: Update.

* New options: --verbatim-files-from, --no-verbatim-files-from
The --verbatim-files-from option instructs tar to treat each line read
from a file list as a file name, even if it starts with a dash.
File lists are supplied with the --files-from (-T) option. By
default, each line read from a file list is first stripped off the
leading and trailing whitespace and, if the result begins with a dash,
it is treated as tar command line option.
Use the --verbatim-files-from option to disable this special handling.
This facilitates the use of tar with file lists created automatically
(e.g. by file(1) command).
This option affects all --files-from options that occur after it in
the command line. Its effect is reverted by the
--no-verbatim-files-from option.
* --null option reads file names verbatim
The --null option implies --verbatim-files-from. I.e. each line
read from null-delimited file lists is treated as a file name.
This restores the documented behavior, which was broken in version
1.27.
