I've been trying to use the program meld as the gmerge tool, but the suggested syntax (as shown in the web ui) is incorrect.

The web ui suggests this syntax for the meld program: meld "%baseline" "%original" "%merge" "%output"

However, that doesn't work. Meld requires a "--output" to specify the output filename. That means the suggested syntax should be this:

meld "%baseline" "%original" "%merge" --output "%output"
