Merge branch 'ignore-crlf-gitmodules' into 'master'

Ignore CRLFs in .gitmodules

.gitmodules files that had CRLFs would cause `blob_content` to fail to lookup the submodule. For example, `ext/apr\n` would not be found when `ext/apr` was the right name.

Closes gitlab-org/gitlab-ce#2262

See merge request !42
