Except when running on Windows. Yes MSYS and cygwin provide a version
of cat, but this cannot be guaranteed (e.g. with the series to support
building with MSVC).
The `--output -` / `-o -` syntax looks reasonable (the issue with
using -f/--force is: what are you forcing the operation of?). Is -
used elsewhere in git for specifying stdout?
Also, the die message might be more useful (and in keeping with the
other git commands) by showing the 'inline context help'; something
like:
Failed to generate the archive: output is a terminal.
Please specify the file to write to (using `-o archive.tar`) or
redirect the output (e.g. `... | gzip`).
If you want to write the archive out to the terminal, use `-o -`
to force the operation.
