config files; repository local and worktree config files and `-c`
command line arguments are not respected.

trace2.normalBrief::
	Boolean.  When true `time`, `filename`, and `line` fields are
	omitted from normal output.  May be overridden by the
	`GIT_TR2_BRIEF` environment variable.  Defaults to false.

trace2.perfBrief::
	Boolean.  When true `time`, `filename`, and `line` fields are
	omitted from PERF output.  May be overridden by the
	`GIT_TR2_PERF_BRIEF` environment variable.  Defaults to false.

trace2.eventBrief::
	Boolean.  When true `time`, `filename`, and `line` fields are
	omitted from event output.  May be overridden by the
	`GIT_TR2_EVENT_BRIEF` environment variable.  Defaults to false.

trace2.eventNesting::
	Integer.  Specifies desired depth of nested regions in the
	event output.  Regions deeper than this value will be
	omitted.  May be overridden by the `GIT_TR2_EVENT_NESTING`
	environment variable.  Defaults to 2.

trace2.configParams::
	A comma-separated list of patterns of "important" config
	settings that should be recorded in the trace2 output.
	For example, `core.*,remote.*.url` would cause the trace2
	output to contain events listing each configured remote.
	May be overridden by the `GIT_TR2_CONFIG_PARAMS` environment
	variable.  Unset by default.

trace2.destinationDebug::
	Boolean.  When true Git will print error messages when a
	trace target destination cannot be opened for writing.
	By default, these errors are suppressed and tracing is
	silently disabled.  May be overridden by the
	`GIT_TR2_DST_DEBUG` environment variable.
