I've given a look at the git-specific convert-repo script. If I get
the idea, the process is just a matter of creating a working directory
and repeating the following loop:

1. "check out" a revision from the old repository (i.e. copy the files
saved "around the same time") into the working directoy
2. hg add missing files (in my case there aren't any 'removals')
3. hg ci in the working directory (or skip 2. and run hg ci -A)
4. goto 1.

until all the revisions are done. Is this correct? In particular, I
was wondering if there isn't a way to insert 'virtual' revisions into
Mercurial without writing the files to disk (in this case by copying
them from their old name).
