with this double quoting, look at PS1 after assignment:

Code:
$ PS1="[$PWD $(git branch | grep '*') $] "
[/home/mute  $] declare -p PS1
declare -- PS1="[/home/mute  \$] "

Your variables are expanded inside of a double-quote before assignment. If you escape the $ then it will be stored inside of PS1. You can also use single quotes to avoid expansion, but you have some in there so those are the 1 character you need to treat special inside single quotes:

Code:
$ PS1='[$PWD $(git branch | grep '\''*'\'') $] '
fatal: Not a git repository (or any of the parent directories): .git
[/home/mute  $]

Having a command execute for each prompt is a bit much. Also maybe you'd like to make it a function and handle those fatal errors in case you leave a git branch.

Code:
[/home/mute/code  $] PS1='[$PWD $(git branch 2>/dev/null | grep '\''*'\'') $] '
[/home/mute/code  $] cd Twitter.awk/
[/home/mute/code/Twitter.awk * master $]

et voila!?

git-annex-shell

git-annex-shell(1)					      General Commands Manual						git-annex-shell(1)

NAME

       git-annex-shell - Restricted login shell for git-annex only SSH access

SYNOPSIS

       git-annex-shell [-c] command [params ...]

DESCRIPTION

       git-annex-shell is a restricted shell, similar to git-shell, which can be used as a login shell for SSH accounts.

       Since  its  syntax  is  identical to git-shell's, it can be used as a drop-in replacement anywhere git-shell is used. For example it can be
       used as a user's restricted login shell.

COMMANDS

       Any command not listed below is passed through to git-shell.

       Note that the directory parameter should be an absolute path, otherwise it is assumed to be relative to the user's home directory. Also the
       first "/~/" or "/~user/" is expanded to the specified home directory.

       configlist directory
	      This outputs a subset of the git configuration, in the same form as git config --list

       inannex directory [key ...]
	      This checks if all specified keys are present in the annex, and exits zero if so.

       dropkey directory [key ...]
	      This drops the annexed data for the specified keys.

       recvkey directory key
	      This runs rsync in server mode to receive the content of a key, and stores the content in the annex.

       sendkey directory key
	      This runs rsync in server mode to transfer out the content of a key.

       commit directory
	      This commits any staged changes to the git-annex branch.	It also runs the annex-content hook.

OPTIONS

       Most options are the same as in git-annex. The ones specific to git-annex-shell are:

       --uuid=UUID
	      git-annex uses this to specify the UUID of the repository it was expecting git-annex-shell to access, as a sanity check.

HOOK

       After  content is received or dropped from the repository by git-annex-shell, it runs a hook, .git/hooks/annex-content (or hooks/annex-con-
       tent on a bare repository). The hook is not currently passed any information about what changed.

ENVIRONMENT

       GIT_ANNEX_SHELL_READONLY

	      If set, disallows any command that could modify the repository.

       GIT_ANNEX_SHELL_LIMITED
	      If set, disallows running git-shell to handle unknown commands.
