make update-po changes line wrapping for japanese translation

[strk]

I don't understand why but if I execute make -C doc/ update-po I end up with a single change in file doc/po/ja/reporting.xml.po which consists in this:

@ -134,8 +134,9 @@ msgid ""
 "a four step process on Unix (assuming you already have <ulink url=\"https://"
 "git-scm.com/\">git</ulink> installed):"
 msgstr ""
-"変更が大きい場合は、パッチが確実に好まれます。Unix上で次の4ステップの処理を行います (既に<ulink url=\"https://git-scm."
-"com/\">git</ulink>をインストールしていると仮定します)。"
+"変更が大きい場合は、パッチが確実に好まれます。Unix上で次の4ステップの処理を行"
+"います (既に<ulink url=\"https://git-scm.com/\">git</ulink>をインストールして"
+"いると仮定します)。"

I cannot read japanese but it looks like being only a matter of where newlines are added. My version of gettext (0.21) seem to make it so that 80 columns are not exceeded.

The line wrapping was EXACTLY like my update-po run would make them before commit [4c3c8e37839127b67dc3f0cf08f67cddc7441d89/git] which seems to be coming from weblate.

I suspect weblate install and my system have a different view about when a line should (or can) be wrapped. Could be locale dependent.

I think we should look at this configuration: ​https://docs.weblate.org/en/latest/admin/addons.html?highlight=output%20page%20width#customize-gettext-output

It looks like my version of gettext by default wraps at 79 cols, but the add-on listed above would allow wrapping at 77 instead, not a custom number

In 641ac33/git:

Update Report-Msgid-Bugs-To to use https

This was the ONLY file still having http instead of https, and
such difference resulted in updating the .po even if the .pot
was not otherwise different, with the side effect of changing
line wrapping.
