[PATCH v3 08/11] sequencer.c: teach append_signoff to avoid adding a duplicate newline

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Teach append_signoff to detect whether a blank line exists at the position
that the signed-off-by line will be added, and avoid adding an additional
one if one already exists.  This is necessary to allow format-patch to add a
s-o-b to a patch with no commit message without adding an extra newline.  A
following patch will make format-patch use this function rather than the
append_signoff implementation inside log-tree.c.
