texi2any not translating @copying contents without @documentlanguage

[Gavin Smith]

While testing other translation problems with texi2any, I stumbled across
another problem.

The following input outputs as expected:

\input texinfo @c -*-texinfo-*-

@documentlanguage fr 
@copying
@defivar copying a b
@error{}
@end defivar
@end copying


@node Top
@top top

@node chap
@chapter Chap

@documentlanguage de

@insertcopying

@bye


The output contains the translation "Instanzvariable" as expected:

1 Chap
******

 -- Instanzvariable of copying: a b
     error→

("of" not "von" due to incomplete translation files.)

However, removing the first "@documentlanguage fr" line prevents the
translation:


\input texinfo @c -*-texinfo-*-

@copying
@defivar copying a b
@error{}
@end defivar
@end copying


@node Top
@top top

@node chap
@chapter Chap

@documentlanguage de

@insertcopying

@bye

This gives:

1 Chap
******

 -- Instance Variable of copying: a b
     error→


There is no justification for this difference, as far as I can tell.
The expansion could arguably be in French or in German, but not in
English.

Note for the first input, the @copying text is correctly translated in
the Info file preamble:

This is test.info, produced by texi2any version 7.1+dev from test.texi.

 -- Variable d'instance de copying : a b
     erreur→
