Johannes Schindelin c839fcff65 import-tars: ignore the global PAX header The tar importer in `contrib/fast-import/import-tars.perl` has a very convenient feature: if _all_ paths stored in the imported `.tar` start with a common prefix, e.g. `git-2.26.0/` in the tar at https://github.com/git/git/archive/v2.26.0.tar.gz, then this prefix is stripped. This feature makes a ton of sense because it is relatively common to import two or more revisions of the same project into Git, and obviously we don't want all files to live in a tree whose name changes from revision to revision. Now, the problem with that feature is that it breaks down if there is a `pax_global_header` "file" located outside of said prefix, at the top of the tree. This is the case for `.tar` files generated by Git's very own `git archive` command: it inserts that header, and `git archive` allows specifying a common prefix (that the header does _not_ share with the other files contained in the archive) via `--prefix=my-project-1.0.0/`. Let's just skip any global header when importing `.tar` files into Git. Note: this global header might contain useful information. For example, in the output of `git archive`, it lists the original commit, which _is_ useful information. A future improvement to the `import-tars.perl` script might be to include that information in the commit message, or do other things with the information (e.g. use `mtime` information contained in the global header as date of the commit). This patch does not prevent any future patch from making that happen, it only prevents the header from being treated as if it was a regular file.
