1. To benefit others who might be looking for something similar may I
post your suggestions as an answer to:
<https://stackoverflow.com/questions/51995773/getting-git-to-show-specific-filenames-it-is-running-content-filters-on>?
2. Is there no way to get git to do the filename reporting as a normal
GIT_TRACE behavior? I don't know anything about its internal workings,
but it surely must knows which file it operates on when it opens it and
sends its data as stdin to the content filter. It makes the debugging so
much easier when one can see what files are being worked on. So perhaps
this utility can be made available to all not just as a hack/workaround.
