Efficient way to check for the changeset of last changes of some file(s)?

That's true only if the files are minority in repo ;-)

> hg log --template "{date} {files}\n" <file1> <file2>

Thanks for the hint, --template indeed simplifies the life a 
little bit. Although I feel I rather need

hg log --template "{rev}:{node|short}:{files}\n" <files>
