Sorry, I disagree.
The availability of this environment variable doesn't help the alias
writer a lot:
1. The alias is still burdened with the task to check *when* to use the
variable, i.e., whether an argument passed is absolute or relative, and
apply the variable only to a relative argument.
2. When more than one pathspec is passed to the alias, it is tedious to
apply $GIT_PATHNAME_PREFIX to each of them.
The only way where this variable could be used in a useful manner is to
write the alias as
!cd "${GIT_PATHNAME_PREFIX:-.}" && { do stuff... ; }
which is something that git should do before it invokes the alias.
