When one of the patches depends on a previous one, it may not be possible to use this hook in a meaningful way. Changing sendemail-validate to take all patches as arguments would break backward compatibility. Add a new hook to allow validating patch series instead of patch by patch. The patch files are provided in the hook script standard input, one per line. Patch file names that contain LF characters are *not* validated. Signed-off-by: Robin Jarry --- Notes: v1 -> v2: - Use `git hook run --to-stdin` with a temp file. - Skip validation (with an explicit warning) for patch file names that contain newline characters. - Updated docs.
