A Git alias to list all files ever tracked in a certain branch

.gitconfig

# Usage: git ls-all [OPTION...] [SINCE..UNTIL]
#
# Options:
#
#   In theory, the command accepts all command line options supported by
#   the  "git log"  command.  In reality, however, only  commit-limiting
#   options are useful. This includes:
#
#     --author=PATTERN, --committer=PATTERN
#         Lists only files that were changed by a certain author.
#
#     --since=DATE, --after=DATE
#         Lists only files that were changed after a specific date.
#
#     --until=DATE, --before=DATE
#         Lists only files that were changed before a specific date.
#
# Examples:
#
#   git ls-all
#       Lists all files that were ever tracked in the current branch.
#
#   git ls-all [email protected]
#       Lists all files that were changed by [email protected].
#
#   git ls-all a185d6b..bdef2c8
#       Lists all files that were changed between  commits  a185d6b  and
#       bdef2c8.
