Git pull with unstated changes

Question

Attempting to pull out git with unspecified changes will fail, saying that you can commit or seal. I assume the workaround is git stash, git pull, then git stash pop. However, is there an alternative way to do this? I would like to force git pull if there are unspecified changes, but only if the files that are downed do not override the changed files? AKA. if I have a repo with the files "derp1", "derp2", "derp3" and locally changed "derp1", the git attraction will destroy and overwrite everything except the derp1 file.

I assume git stash + pull + stash pop achieves this already? And is there a better way?

I believe this can also work differently if it occurs on a submodule.

The latest git versions seem to do what you ask

see the following commands:

( [foo]$before the command indicates that it is running in the directory foo)

[tmp]$ git --version
git version 2.0.0
[tmp]$ git init foo
Initialized empty Git repository in /tmp/foo/.git/
[tmp]$ cd foo
[foo]$ echo hello > file1
[foo]$ echo world > file2
[foo]$ git add .
[foo]$ git commit -m "first commit"
[master (root-commit) 5f7d6b3] first commit
 2 files changed, 2 insertions(+)
 create mode 100644 file1
 create mode 100644 file2
[foo]$ cd ..
[tmp]$ git clone foo bar
Cloning into 'bar'...
done.

Here, I initialize the two repositories foo, and bar, barthat is a clonefoo

Now lets you model non-conflict change

[tmp]$ cd foo
[foo]$ echo Hello > file1
[foo]$ git commit -am "correct hello > Hello"
[master 183c4a5] correct hello > Hello
 1 file changed, 1 insertion(+), 1 deletion(-)
[foo]$ cd ../bar
[bar]$ echo "world !" > file2
[bar]$ git st 
On branch master
Your branch is up-to-date with 'origin/master'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   file2

no changes added to commit (use "git add" and/or "git commit -a")

If we pull now, everything will be smooth

[bar]$ git pull
remote: Counting objects: 3, done.
remote: Compressing objects: 100% (2/2), done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.

 file1 | 2 +-
 1 file changed, 1 insertion(+), 1 deletion(-)
[bar]$ git st

    modified:   file2

no changes added to commit (use "git add" and/or "git commit -a")

However, with a conflicting change (remember that we have a file without a binding file2in a line containing only a word world)

[bar]$ cd ../foo/
[foo]$ echo World > file2
[foo]$ git commit -am "add World"
[master 7cb10c9] add World
