Hi.

Is there a way to avoid having these to file to always show up as non-staged?

$ git status
# On branch cat
# 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:   externals/httplib2 (new commits)
#       modified:   scripts/i18n (new commits)

Some files in a repository, which are versioned (i.e. they can't be git-ignored), are often changed,
but rarely committed. Usually these are various local configuration files that are edited,
but should never be committed upstream.

Git lets you ignore those files by assuming they are unchanged. This is done by running the
    git update-index --assume-unchanged path/to/file.txt
