+The current trend is to have the name of the current git branch everywhere. Personnaly I display it in my vim's status bar, and in my zsh prompt.
+
+Here is my vimrc configuration for this (I'm not the author of this function, and can't remember where I saw it first):
+
+``` viml
+set statusline=%<[%n]%m%r%h%w%{'['.(&fenc!=''?&fenc:&enc).':'.&ff}%{g:gitCurrentBranch}%{']'}%y\ %F%=%l,%c%V%8P
+autocmd BufEnter * :call CurrentGitBranch()
+
+let g:gitCurrentBranch = ''
+function! CurrentGitBranch()
+    let cwd = getcwd()
+    cd %:p:h
+    let branch = matchlist(system('/usr/local/git/bin/git  branch -a --no-color'), '\v\* (\w*)\r?\n')
+    execute 'cd ' . cwd
+    if (len(branch))
+        let g:gitCurrentBranch = '][git:' . branch[1] . ''
+    else
+        let g:gitCurrentBranch = ''
+    endif
+    return g:gitCurrentBranch
+endfunction
+```
+
+and my zshrc:
+
+``` sh
+local git_b
+git_b='$(get_git_prompt_info '%b')'
+PROMPT="%(?..%U%?%u:) $git_b %40>...<%/%(#.%U>%u.%B>%b) "
+```
+
+with the following script [S55\_git](http://www.jukie.net/~bart/conf/zsh.d/S55_git).
