As you might have guessed, git pull is actually a shortcut to two commands one after the other: git fetch (to get any new commits from the remote repository) and git merge (to merge the files in the remote branch with the current local one). Unlike with doing things by hand, it's actually quite hard to over-write files and lose work. Git will not let you pull in other people's changes until you have committed yours, and it will not let you push your changes to a remote repository until you have first pulled its changes in and merged them. And finding old versions by your commented history is much easier than trying to remember the meaning of your own filenames!

Here's a good way to go about fixing it: 1) Make a branch to contain the fixed code, with something like "git checkout -b betterlayout" . 2) Edit the code and commit and push your changes, with "git push origin betterlayout". This makes a corresponding branch, aussi called "betterlayout" on the remote repo "origin". 3) Go to the repo's page on GitHub. It will probably prompt you to "submit a pull request" - if it doesn't, select the "betterlayout" branch from the "branch:" menu next to the repo name. 4) Click on the button to start a pull request. An issue-like form will appear, where you can edit the title of the pull request (eg "Better LaTeX Layout?") and provide some comment on what what you have done and why. 5) Submit the pull request with the button at the bottom of the form. This will notify the repo's owner, and everyone else who is watching the repo, that you have made some changes and would like them to be merged into the code.
