+ add pointer-check when closing piped input (cf: 2007/03/25)
+ use here-documents rather than echo, when passing backslashes in
strings, to accommodate the Debian shell "dash" (Debian #489563).
+ recode several ".po" files to UTF-8 for consistency.
+ change --separator to be an alias for --output-separator, for
compatibility with Xdialog.
+ add --output-separator option to allow scripts to change the output
separator from a newline (for --separate-output) or a space. This
applies to other widgets such as forms and editboxes which normally
use a newline.
+ add --column-separator option, to tell where column-aligned data for
radio/checkboxes or menus should be split into columns (request by
Ben Dibbens).
+ add id.po, ku.po, lt.po, nb.po and update ca.po, fr.po, gl.po, ja.po,
th.po from
http://translationproject.org/latest/dialog/
+ add "--quoted" option, to quote values returned by formbox, etc.
+ change names of EX/ES macros in dialog.1 to work around name-
pollution caused by changes in Debian #470729.
