That said, I really miss this feature too (the ability to see at a
glance all the branches/tags/... a certain revision was copied to,
f.i. when looking at the log of a file).
It's true that this is not possible with SVN currently, because the
repository doesn't keep track of "copy_to" information (where was this
file copied to), only "copy_from" information (where was this file
copied from). So you can only "calculate" the copy_to information by
analyzing the entire history of the repository, and deduce this info
(some clients and third-party software do this stuff, to create
revision graphs and such (e.g. TortoiseSVN)).
Full support for this kind of question will have to wait for major
changes to the SVN back-end filesystem, so it keeps track of the
copy_to information. Maybe it's something that will be considered for
FS-NG in the not-so-near future (see
http://subversion.apache.org/roadmap.html and take a look at the "most
wanted features", where it says "Forward history searching").
However, the following question can still be answered easily with
current SVN: "Given tag X, which revision of file Y was included?"
Very often the above general question ("which tags was this (version
of a) file copied to?") can be rephrased to a question about a
specific tag (e.g. you want to know if your bugfix is included in a
certain release (tag X) or not).
