affects only 'git diff' Porcelain, and not lower level
'diff' commands such as 'git diff-files'.
+diff.dirstat::
+ A comma separated list of `--dirstat` parameters specifying the
+ default behavior of the `--dirstat` option to linkgit:git-diff[1]`
+ and friends. The defaults can be overridden on the command line
+ (using `--dirstat=<param1,param2,...>`). The fallback defaults
+ (when not changed by `diff.dirstat`) are `changes,noncumulative,3`.
+ The following parameters are available:
++
+--
+`changes`;;
+ Compute the dirstat numbers by counting the lines that have been
+ removed from the source, or added to the destination. This ignores
+ the amount of pure code movements within a file. In other words,
+ rearranging lines in a file is not counted as much as other changes.
+ This is the default behavior when no parameter is given.
+`lines`;;
+ Compute the dirstat numbers by doing the regular line-based diff
+ analysis, and summing the removed/added line counts. (For binary
+ files, count 64-byte chunks instead, since binary files have no
+ natural concept of lines). This is a more expensive `--dirstat`
+ behavior than the `changes` behavior, but it does count rearranged
+ lines within a file as much as other changes. The resulting output
+ is consistent with what you get from the other `--*stat` options.
+`files`;;
+ Compute the dirstat numbers by counting the number of files changed.
+ Each changed file counts equally in the dirstat analysis. This is
+ the computationally cheapest `--dirstat` behavior, since it does
+ not have to look at the file contents at all.
+`cumulative`;;
+ Count changes in a child directory for the parent directory as well.
+ Note that when using `cumulative`, the sum of the percentages
+ reported may exceed 100%. The default (non-cumulative) behavior can
+ be specified with the `noncumulative` parameter.
+<limit>;;
+ An integer parameter specifies a cut-off percent (3% by default).
+ Directories contributing less than this percentage of the changes
+ are not shown in the output.
+--
++
+Example: The following will count changed files, while ignoring
+directories with less than 10% of the total amount of changed files,
+and accumulating child directory counts in the parent directories:
+`files,10,cumulative`.

diff.external::
If this config variable is set, diff generation is not
performed using the internal diff machinery, but using the
A boolean to inhibit the standard behavior of printing a space
before each empty output line. Defaults to false.
-diff.tool::
- Controls which diff tool is used. `diff.tool` overrides
- `merge.tool` when used by linkgit:git-difftool[1] and has
- the same valid values as `merge.tool` minus "tortoisemerge"
- and plus "kompare".
-
diff.<driver>.command::
The custom diff driver command. See linkgit:gitattributes[5]
for details.
diff.<driver>.cachetextconv::
Set this option to true to make the diff driver cache the text
conversion outputs. See linkgit:gitattributes[5] for details.
+
+diff.tool::
+ The diff tool to be used by linkgit:git-difftool[1]. This
+ option overrides `merge.tool`, and has the same valid built-in
+ values as `merge.tool` minus "tortoisemerge" and plus
+ "kompare". Any other value is treated as a custom diff tool,
+ and there must be a corresponding `difftool.<tool>.cmd`
+ option.
