git-prompt.sh: allow to hide prompt for ignored pwd

Browse Source 
Optionally set __git_ps1 to display nothing when present working
directory is ignored, triggered by the new environment variable
GIT_PS1_HIDE_IF_PWD_IGNORED. This environment variable may be
overridden on any repository by setting bash.hideIfPwdIgnored to
"false". In the absence of GIT_PS1_HIDE_IF_PWD_IGNORED this change
has no effect.

Many people manage e.g. dotfiles in their home directory with git.
This causes the prompt generated by __git_ps1 to refer to that "top
level" repo while working in any descendant directory. That can be
distracting, so this patch helps one shut off that noise.
