File renaming caused colliding pathnames

[kinke]

Hi,

I tried this with git-filter-repo v2.25:

$ git clone https://github.com/dlang/dmd.git
$ cd dmd
$ git-filter-repo --subdirectory-filter test
Parsed 22266 commitsFile renaming caused colliding pathnames!
  Commit: b'4473071207c78d691f7ed2ec4713172663f3bea8'
  Filename: b'README.md'
fatal: stream ends early
fast-import: dumping crash report to .git/fast_import_crash_1734

I've then tried to work around it; removing the trailing slash passes a --dry-run (no errors during commits parsing), but then yields

$ git-filter-repo --path test/ --path-rename test/:
same as above
$ git-filter-repo --path test --path-rename test:
Parsed 333 commitsfatal: Empty path component found in input
fast-import: dumping crash report to .git/fast_import_crash_2000
Traceback (most recent call last):
...
BrokenPipeError: [Errno 32] Broken pipe

A similar git filter-branch cmdline I'm trying to replace works:

git filter-branch --tag-name-filter cat --prune-empty --subdirectory-filter test -- --all

Well, that was a pretty embarrassing bug. Thanks for the nice clear report and testcase; you made it very easy to track down. Fixed with the commit I just pushed.

Thanks for the super-quick fix!
