dpkg-source removes it, by default, for 3.0 based formats as it's part
of the default ignore list.
(or rather ignores it)
$ apt-get source hello
$ cd hello-*
$ cat debian/source/format
3.0 (quilt)
$ git init
$ echo "*.a" > .gitignore
$ git add .
$ git commit -m "initial"
$ debuild -S
$ dpkg-source -x ../hello*.dsc
$ cat hello-*/.gitignore
ls: cannot access hello-2.8/.gitignore: No such file or directory
Ideally "packaging .gitignore" would be in debian/gitignore, but I
don't know if that will work.
This is a problem, because it breaks the round-trip guarantees between
dgit, git, dsc. That is, unpacking source package does not re-create
matching git tree sha.
