# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
# find one, or @{upstream} otherwise. Once you have set
# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
# contains relative to newer annotated tag (v1.6.3.2~35)
# branch relative to newer tag or branch (master~4)

# If you would like a colored hint about the current dirty state, set
# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
# the colored output of "git status -sb" and are available only when
# using __git_ps1 for PROMPT_COMMAND or precmd.
+#
+# If you would like __git_ps1 to do nothing in the case when the current
+# directory is set up to be ignored by git, then set
+# GIT_PS1_HIDE_IF_PWD_IGNORED to a nonempty value. Override this on the
+# repository level by setting bash.hideIfPwdIgnored to "false".
