Right.

It was replaced along the way. This very same tree /importfromcvs/trunk
was used to import completely unrelated projects. Then moved, so it did
not exist all the way.

In my case the previous version on this tree was 45546. There is nothing
in between 45546 and 45775 for example. So looking at any revision in
between return an error:

$ svn log -v svn+ssh://myserver/importfromcvs/trunk@45760
svn: File not found: revision 45760, path '/importfromcvs/trunk'

Looks like it is the case. Hence the reported errors:

W: Ignoring error from SVN, path probably does not exist: (160013):
Filesystem has no item: File not found: revision 100, path '/trunk/PROJ'

and

W: Ignoring error from SVN, path probably does not exist: (160013):
Filesystem has no item: File not found: revision 101, path
'/importfromcvs/trunk'

For sure there was no revision 101 on /importfromcvs/trunk:

$ svn log -v svn+ssh://myserver/importfromcvs/trunk@101
svn: File not found: revision 101, path '/importfromcvs/trunk'

No it works on my case. That's what I'm using to import the directory in
two steps. I just want to go to the bottom of this to see if we can
somehow improve git-svn.

I'm not sure to understand what you are proposing here. To look only at
parents that are directly "related" to the current branch ?

Thanks,
Pascal.
