Subject: [PATCH] mergetools/meld: improve compatibiilty with Meld on macOS X

The macOS X fork of Meld[1] requires a "=" in the "--output"
argument, as it uses a wrapper[2] script that munges the
"--output" argument before calling into the common "meld"
script.

The macOS X wrapper script[2] accepts "--output=<filename>"
only, despite the fact that the underlying meld code accepts
both "--output <filename" and "--output=<filename>"[3].

All versions of meld which accept "--output" accept it in
the "--output=<filename>" form, so use "--output=<file>" for
maximum compatibility.
