The precise wrapping behaviour depends on the version of GNU libunistring
in use. "In use" means:
  - if msgattrib is dynamically linked against libunistring
    (see "ldd msgattrib"), that version of libunistring.so,
  - if not, then the version of libunistring that was partially included
    in the GNU gettext source code.

So, there are 4 scenarious in which the same gettext version on different
machines may behave differently:
  - msgattrib is linked against a libunistring.so on both machines,
    and a new version of libunistring was installed on one of the two machines
    but not both.
  - msgattrib is linked against a libunistring.so on one of the machines,
    and a new version of libunistring was installed on this machine later.
  - msgattrib is linked against a libunistring.so on both machines,
    and they use different versions, and due to a bug in gettext's build
    process the installed libunistring.so was used instead of the
    sources included in the GNU gettext source code.
  - msgattrib is linked against a libunistring.so on one of the machines,
    and on this machine, due to a bug in gettext's build process the installed
    libunistring.so was used instead of the sources included in the GNU gettext
    source code.

If you don't require that the PO files be directly editable by a
translator, you can just use the option --no-wrap.
