[bug-gettext] update-po always recreates address@hidden and address@hidden when --no-wrap is used

[Simon Sobisch]

I'm using msgmerge (GNU gettext-tools) 0.19.8.1 (and used gettexize with
the same version).

With recent autotools (which uses a read-only source for `make
distcheck`) I cannot use --no-wrap any more with the "languages"
address@hidden and address@hidden

Tested:

* removed --no-wrap completely:
--> all language files get renewed once, additional runs of `make
update-po` don't change any of them

* added --no-wrap to MSGMERGE_OPTIONS, XGETTEXT_OPTIONS and MSGINIT_OPTIONS
--> all language files get renewed once, additional runs of `make
update-po` always recreates address@hidden and address@hidden

Do you have any ideas to fix this issue?

Simon

BTW: Why isn't it enough to add --no-wrap to only MSGMERGE_OPTIONS and
it should be added to XGETTEXT_OPTIONS and MSGINIT_OPTIONS, too?
