That was in 2002, so at that time we were using CVS, and we converted
the repository to Subversion with cvs2svn on 2005-10-24.

But when I detected this issue, this was with a local mirror, thus
with a repository that has been rebuilt a few weeks ago on a machine
with Subversion 1.14.0.

You may be running into this (quoting from svn_fs_contents_changed()'s 
docstring):

 * @note svn_fs_contents_changed() was not designed to be used to detect

 * contents of a given file have changed across two points in its history.
 * For the purposes of preserving accurate history, certain bits of code

 * svn_fs_contents_different().  See issue 4598 for more details.

Or maybe that revision was created by a pre-1.0 version of Subversion
that had some bug or another.

svn log says text-mods="true" but there are no diffs

[Vincent Lefevre]

I get the following:

$ svn log --xml -v -r 1984 https://scm.gforge.inria.fr/anonscm/svn/mpfr

vlefevre
2002-07-23T16:22:08.00Z

/trunk/mul.c

Fixed permissions.




I'm wondering why text-mods="true" while

  svn diff -c 1984 https://scm.gforge.inria.fr/anonscm/svn/mpfr

shows no diffs.
