This changes the configuration syntax for defining a low-level merge driver to be: [merge "<<drivername>>"] driver = "<<command line>>" name = "<<driver description>>" which is much nicer to read and is extensible. Credit goes to Martin Waitz and Linus. In addition, when we use an external low-level merge driver, it is reported as an extra output from merge-recursive, using the value of merge.<<drivername>.name variable. The demonstration in t6026 has also been updated. Signed-off-by: Junio C Hamano <junkio@cox.net>
