如何导入一系列提交我git快速导出到快速导入的文件？

Question

我通过git fast-export使用：

导出了一系列提交（分支）

$ git fast-export master...zzz-utumno-refactoring_master > my_original_utumno_r\
efactoring_master_branch_before_rebases

现在我正在尝试重新导入它。我得到的最接近的是：

$ cat my_original_utumno_refactoring_master_branch_before_rebases | git fast-im\
port
fatal: Branch name doesn't conform to GIT standards: master...zzz-utumno-refacto
ring_master
fast-import: dumping crash report to .git/fast_import_crash_4268

编辑：还尝试过：

$ git fast-import < my_original_utumno_refactoring_master_branch_before_rebases
fatal: Branch name doesn't conform to GIT standards: master...zzz-utumno-refacto
ring_master
fast-import: dumping crash report to .git/fast_import_crash_4720

git-fast-import没有给我任何线索。我该怎么办？

我不太了解的一些链接：

• Malformed branch name in fast-export when specifying non-HEAD/branch revision
• Import changes into a git repository from universal diff
• Using git fast-export to export a repo starting at a given commit
