How Mercurial solves problem of multiple _persistent_ branches? Does it
add pointers to commits somewhere deeper in changelog / revlog?

Each changeset may have a branch marker.

Here's branches in use with an import of mutt's CVS history:

$ hg branches
mutt-0-94                      208:b2cc0abd8fe0
HEAD                           207:a505693b54c1
mutt-0-93                      134:d59345944030
muttintl                       1:29510de8b3fc
$ hg co HEAD
176 files updated, 0 files merged, 8 files removed, 0 files unresolved
$ hg branch
HEAD
$ hg branch devel
$ hg branch
devel
$ hg branch devel

BTW does Mercurial have tags?

Yes. Both local and revision-controlled.

Nice to know. You compress only file deltas, or also file revision
metadata? Do you compress manifests (trees) and commits (or at least
commit messages) too?

All three use the same underlying storage format, so yes.
