Currently a plain 'git checkout .' will revert any local changes, e.g.
% mkdir test
% cd test
% git init
Initialized empty Git repository in /home/eda/test/.git/
% echo hello >foo
% git add foo
% git commit -m.
[master (root-commit) 34f6694] .
1 file changed, 1 insertion(+)
create mode 100644 foo
% echo goodbye >foo
% git checkout .
% cat foo
hello
I suggest this is dangerous and by default 'git checkout' should only alter
files which do not have local changes (as would be reported by 'git diff').
Only if --force is given should working tree differences be thrown away.
% git --version
