Hello Alexey,

thank you very much for your reply. I felt I did something wrong, but couldn't find out what it was. Actually it turned out that I had just mistyped one tag name.

Also it seems that both syntaxes work:
git diff v0.4..v0.5
git diff v0.4 v0.5

The question is: How does git disambiguate between tag names, commits and file names? (All may start with a letter)
This seems to work automagically, and I was desparately looking for an option like "--" to separate revisions from file names. I found "SPECIFYING REVISIONS" in git-rev-parse(1), so you don't really have to answer.

Regards,
Ulrich
