@Stefan: Thanks for letting me know the version you tried on.

I have the following:
Gitolite version: gitolite3 v3.04-13-gcc9727c-dt on git 1.7.1
Git server version: git version 1.7.1
Git client version: git version 1.9.4.msysgit.2

My Git server version lags quite behind compared to yours. :) Clone of
any repository is not empty because i create non-empty directories
while creating any repository.

@Matthieu: You were right in saying that client can get confused if
several branches point to same commit. :)  Thank a ton! :) Going by
what Jeff mentioned confidently, my server version (1.7.1) indeed has
that flaw.

@Jeff: You've hit the nail on the head! :) Both Matthieu & you are
right. I even confirmed the same by changing the content of mainline
while initializing repository. SHAs indeed became different for both
master and mainline. Now when i clone the repository on my local
machine, it correctly points to mainline. And special thanks for
pointing to the exact Git version where the flaw was fixed. :) I
checked the release notes too. :)

Thank you guys! You rock!!!
