git-svn's standard ref structure makes it easy to shoot yourself into
the foot, and so does "--mirror". Combining the two is really a powerful
weapon :)

$git ls-remote   git://github.com/graemeg/freepascal.git
840169d189370c3b08760654800990404b2218df        HEAD
840169d189370c3b08760654800990404b2218df        refs/heads/master
3a5d5a06bbe62fada139c86438348e30ff4fcbe7        refs/remotes/aspect
f8a21acf439e698e7cb57a2a68401cfca2486c0c        refs/remotes/avr
78d1c138d4755f26ae1515842fcf36f13bf6b030        refs/remotes/cleanroom
b2701a7710bc343257b47738a06cb1290cec902f        refs/remotes/cpstr
92c78d3c8efe0bce64fda3f949596f37465bb6bb        refs/remotes/ctypes

etc.

You really mirrored your repo: All your "lost" branches are remotes on
the github side as well. That has two consequences:

1) They're not shown in the shiny interface.
2) They don't get cloned when someone clones from there.

At least 2) is completely unrelated to github, btw.

I think what you really want is to push everything under remote
(assuming there are only svn branches) into proper heads on github, i.e.
a refspec like '+refs/remotes/*:refs/*' for your pushes.

I assume you want to push master only if it differs from trunk, i.e. if
that repos is going to host not only the svn mirror but also your
additions. (I don't recommended that, a fork is better for that.)
