This was not this bug. What I did was to change svn:keywords from
"Id Date" to "Id" on various files (which used only the Id keyword),
and the commit did only that. But for some of these files (those
that did not have any additional commits later), the expansion of
the Id keyword was still the one from the previous commit. In #4585,
the svn:keywords does not change, which triggers a bug. But here,
svn:keywords had changed.
The commit was done in December 2017 on a Debian/stable machine.
The svn version was 1.9.5 (Debian package 1.9.5-1+deb9u1), and
the working copy was on the same machine.
Now the machine has svn 1.10.4, but for files that didn't had new
commits, "svn up" on the working copy doesn't change anything, so
that these files were still affected by the old issue.
I've just tried to reproduce the bug with the following script:
------------------------------------------------------------
#!/bin/sh
set -e
mkdir my-test-svn
cd my-test-svn
svnadmin create svn
svn co file://`pwd`/svn wc1
svn co file://`pwd`/svn wc2
cd wc1
mkdir dir
printf '# \044Id\044\n' > dir/file
svn add dir
svn propset svn:keywords "Id Date" dir/file
svn ci -m "add dir/file"
svn update
cat dir/file
cd ../wc2
svn update
cat dir/file
svn propset svn:keywords "Id" dir/file
svn ci -m "new keywords"
cat dir/file
svn update
cat dir/file
cd ../wc1
svn update
cat dir/file
------------------------------------------------------------
on a machine that has svn 1.9.4 (gcc119.fsffrance.org), but
I haven't noticed any issue (I expected the 3rd and 4th cat
output to be incorrect).

No, this is never done. You can try by changing the Id keyword
expansion of a file. A "svn update" never fixes it to the correct
value.

Ditto.
