## The symptom
On Windows, `ggshield secret scan pre-commit` crashes with:
```
[WinError 206] The filename or extension is too long
```
when committing a merge with many files and long file names. ggshield builds a
git command line that exceeds Windows path limits.
## The fix
A fix was merged and shipped in the release after the report, shortening how
the git command is constructed. The reporter tested the fix branch and confirmed
it resolves the crash. Upgrade ggshield to a release newer than the report:
```
pip install --upgrade ggshield
```
## The general lesson
WinError 206 on a pre-commit hook, when the same hook works on smaller commits,
is almost always a command-line length problem, not a file problem. Tools that
pass file lists as argv hit it; the fix is on the tool side.
