feature proposal: named branches without named branches

[Uwe Brauer]

Hi

I recently found out that git, which does only have bookmarks, has a
feature (name-rev) which allows to display the log and its bookmarks «as if they
were named branches»

The following

git log --graph --decorate --pretty=short | git name-rev --stdin | more

Does the trick

Resulting for example for the auctex repository in 

* commit eb2d64bede8587c864c3031f233a0ae87c3f3a03 (master) (HEAD, origin/master, origin/HEAD, master)
| Author: Mosè Giordano <mose at gnu.org>
|
|     Fix to my previous commit
|
*   commit 17d1a5d71f9fb6adbb90e17dbf223f3bf1e2f92a (master~153)
|\  Merge: f9efa73 1950012
| | Author: Mosè Giordano <mose at gnu.org>
| |
| |     ; Merge branch 'simplify-TeX-parse-error'
| |
| *   commit 1950012155d539f05c393dae3d6e93548bbc57b2 (remotes/origin/simplify-TeX-parse-error~136)
| |\  Merge: b4ff376 4b21d3f
| | | Author: Tassilo Horn <tsdh at gnu.org>
| | |
| | |     Merge branch 'master' into simplify-TeX-parse-error


So the () after the HASH indicate to which branch a commit belongs.

(I admit that I find the corresponding graph using mercurial+named
branches cleaner and leaner.)

Could a similar feature be implemented in mercurial? Most likely it
would make named branches obsolete.
