Make the mergetool used with "meld" backend behave similarly to "vimdiff" by
telling it to auto-merge non-conflicting parts and highlight the conflicting
parts when `mergetool.meld.useAutoMerge` is configured with `true`, or `auto`
for detecting the `--auto-merge` option automatically.

Enable auto-merge for meld to follow the vimdiff beharior
Hi, the mergetool "meld" does NOT merge the no-conflict changes, while
the mergetool "vimdiff" will merge the no-conflict changes and highlight
the conflict parts. This patch will make the mergetool "meld" similar to
"vimdiff", auto-merge the no-conflict changes, highlight conflict parts.

+mergetool.meld.useAutoMerge::
+ When the `--auto-merge` is given, meld will merge all non-conflicting
+ parts automatically, highlight the conflicting parts and wait for

+ Git to unconditionally use the `--auto-merge` option with `meld`.
+ Setting this value to `auto` makes git detect whether `--auto-merge`
