git-mv ignores gitignore file
gitignore(5) manual says that
Quoted 5 lines
A gitignore file specifies intentionally untracked files that Git should ignore. Files already tracked by Git are not affected ...
The purpose of gitignore files is to ensure that certain files not tracked by Git remain untracked.
which means that the following operations are totally correct.
$ echo "b" >> .gitignore $ echo "Something" > a $ git add a $ git mv a b
Equivalantly,
$ echo "b" >> .gitignore $ echo "Something" > b $ git add --force b
That is, doing something --force when --force it is not specified.
However, this may not be the intented behavior. The user might not want to equivalantly add a `new' file b to the index when b should be gitignored. Such operations are possibly oversight of users.
The ideal behavior, issue a warning when git-mv target collides with gitignore.
Thanks.
