External paths for subrepositories

[Vasiliev Vladimir]

Hello.
I use subrepositories and have found them quite inconvenient to track 
changes locally and at bitbucket.org.

Method of setting .hgsub as "Shared = ../Shared" works, but, as i see, 
it is not very good for working (e.g. cloning) local (another example: 
if i want to push to other repos, the copy of subrepository at the same 
level, as main repository, will be updated with changesets, not the 
subrepository itself) I saw at hgrc/subpaths then, but, regretfully, 
they work only with right parts of .hgsub.

It would be great, if they worked with entire path after substitution - 
it is just what i expected. It will make subrepositories much more 
flexible, then now, because regular expression allow to set

In this case, for .hgsub "shared=shared" i would use following subpath 
section for my bitbucket account:
[subpath]
https://bitbucket.org/user/repository/shared = 
https://bitbucket.org/user/shared
Then any problems with local work would end.


Another idea, that I see as good decision for this problem, if i set 
.hgsub as "../shared = ../shared" - then shared repository will be 
always at the same level, as main repository (like at bitbucket). But 
when i tried to do this, mercurial returned error:
"abort. path contains illegal component: ../shared"

Can anyone answer, could at least one of these two features be 
implemented in mercurial?
