Git aliases generalized for svn also

[Lilian Besson (Naereen)]

I use extensively the aliases s, v, p and c for git status, pull, push, commit. With something as simple as:

function s() {
  git status "$@" || svn status "$@"
}

and so on, it should be possible to generalize them so these aliases can work in a git and a svn repository, similarly. (so, no need to learn the svn commands!)
