Prevent git commits that miss files included in a LaTeX project

pre-commit

#!/bin/bash
# Git pre-commit hook to look for untracked files mentioned in the LaTeX and BibTeX logs.
# Fail if any are found. Note that this is not foolproof, as included .tex files
# not generating any errors or warnings may not be mentioned in the log.
#
# Goes in file .git/hooks/pre-commit under the repository root.
