The "sphinx-intl update" command should not change existing msgstr

[greyli]

Hi! I followed the instructions in the Sphinx docs to generate the .pot and .po files in this repo.

Now after the .rst source has changed, I tried to update the .po files with the following commands:

$ make gettext
$ sphinx-intl update -p _build/gettext

But I found some unexpected changes (flaskcwg/flask-docs-zh#35):

• Some Chinese words added as msgid for the API reference docs (ref).
• The msgid of alt of images was replaced with the translated msgstr (ref).
• Some multiline msgstr was reordered based on the position of the English word (ref).

The last one brings quite a bit messy (see the ref for the example). Is there any method to disable the update command to change the existing msgstr? I didn't found any related issues or documentation. And the -w option only changes the max line length of msgid.

Sphinx: 4.0.2
sphinx-intl: 2.0.1
Python: 3.8 (Windows 10)

Thanks!

Some Chinese words added as msgid for the API reference docs (ref).
The msgid of alt of images was replaced with the translated msgstr (ref).

At present, your .pot file is built with language=zh_CN. So it contains Chinese text as msgid.
Please generate .pot file with language=en (or None).

Some multiline msgstr was reordered based on the position of the English word (ref).

This is a bug of babel; a library that sphinx-intl uses to re-generate .po file. And I don't know a workaround for this topic:

Could you file an issue to the project, please?

Could you file an issue to the project, please?

My colleague in the translation team has already submitted the issue to babel (python-babel/babel#787). Thanks!
