[BUG] git config: cygwin git version 1.6.1.2 does not deletes empty sections

I have encountered a bug related to git config in cygwin git version 1.6.1.2

The git config --unset might leave an empty section when the last property is deleted. But consequent "git config key value" does not uses this empty section. So the following script leaves a sequence of empty sections "[a]". Looks like a disk space leak to me.

git config a.b a git config --unset a.b git config a.b a git config --unset a.b git config a.b a git config --unset a.b git config a.b a git config --unset a.b

The resulting .git/config file:

[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
	logallrefupdates = true
	ignorecase = true
[a]
[a]
[a]
[a]

Was this bug fixed in later versions?
