[PATCH] Ask git for its toplevel directory directly

[Clemens Hammacher <hammacher@cs.uni-saarland.de>]

This avoids printing the wrong base directory if $PWD contains a
symlink. If /tmp is the base and $PWD is /tmp/b, where b is a symlink
(to "." or any other directory), git rev-parse --show-prefix will show
the link target instead of b. Thus the replacement in $PWD does not
work.
Fortunately, there also exists git rev-parse --show-toplevel, which
reliably returns the base directory.
