Node:Merging Incomplete Lines, Next:Saving the Changed File, Previous:Bypassing ed, Up:diff3 Merging
diff3 Merges Incomplete LinesWith -m, incomplete lines (see Incomplete Lines) are simply
copied to the output as they are found; if the merged output ends in an
conflict and one of the input files ends in an incomplete
line, succeeding |||||||, ======= or >>>>>>>
brackets appear somewhere other than the start of a line because
they are appended to the incomplete line.
Without -m, if an ed script option is specified and an
incomplete line is found, diff3 generates a warning and acts as
if a newline had been present.
