X-Git-Url: https://git.r.bdr.sh/rbdr/mobius/commitdiff_plain/3e20402491f013710dfa1c2f3d0cd6ab0e212585?hp=1a37f0144d0fd777771c6d870e3c3298947e2712

Fix corrupt file info forks

This fixes a bug that happens when:

1. Optional "Enable Resource Forks" feature is true
2. A file comment is added
3. The comment is updated to be shorter than the original

The expected behavior is that the hidden .info file is replaced with the new data, but this wasn't happening because the file flag was not set to truncate on write.
