This sentance makes no sense at all, go away and learn english PLEASE!
1. If providing a diff satisfies any requirement of the *GPL, is a question
for which you should consult a lawyer not a programmer and not the FSF.
2. A diff is easier for us, as well as for the "other side" than having
modification dates and names in every single file.
3. Providing no modification trace at all neither
diff/(modification dates+names)/git nor oterwise is a breach of the LGPL
that is one of the things we complained about and what the FSF told you.
4. I(We?) consider diff(s) + source svn + revission to be sufficient to
5. The FSF considers correct names+dates of any change in each
file to be sufficient to fullfill 2b
6. The FSF has no ownership in ffmpeg and are not in a position to
demand anything from anyone. We though do.
7. I(We?) have no interrest in enforcing the FSF interpretation of the *GPL
This would not be in anyones interrest short of the FSFs.

You really have a problem with your understanding, GOM is currently not
compliant to the LGPL AFAIK. As such if you take their code and redistribute
with or without modifications (no matter what kind of) you are breaking
copyright laws because you cannot have a LGPL license which GOM did not have
in the first place.
If GOM where compliant to the LGPL you could of course take their
source and modify and redistribute it within the LGPL rules.
Assuming GOM was compliant, either you stay compliant
by providing a modification trace or you loose this information/
not add new notes as needed.
You could for example provide a diff together with goms diff(s)+svn rev. You
could also analyze the diff(s) from gom and convert that to dates + names
and add your name + date of modification. Also you could just use a revission
control system like git or mercurial to keep track of all changes.
What you cannot do is take a file from gom and remove the modification
information without providing the information in some other form.
Note: Iam not a lawyer above is just my uneducated oppinion!
