Some platforms (like SunOS and family) have kept their common binaries at some historical moment in time, and introduced new binaries with modern features in a special location like /usr/xpg4/bin or /usr/ucb. Some of the features provided by these modern binaries are expected and required by git. If the featureful binaries are not in the users path, then git could end up using the less featureful binary and fail. So provide a mechanism to prepend elements to the users PATH at runtime so the modern binaries will be found.
