fix statfs divide-by-zero when blksize is 0#350
Merged
Conversation
On macOS, sshfs.blksize is set to 0. The statfs fallback path (used when the server lacks the statvfs extension) divides by f_frsize, which inherits that zero. Use 4096 as the default.

Use 4096 as the default when blksize is unset.
No test: this needs macOS blksize=0 plus a server without statvfs, which CI does not cover.
