run-command: show prepared command
This adds a trace point in start_command so we can see the full
command invocation without having to resort to strace/code inspection.
For example:
$ GIT_TRACE=1 git test foo
git.c:755 trace: exec: git-test foo
run-command.c:657 trace: run_command: git-test foo
run-command.c:657 trace: run_command: 'echo $*' foo
run-command.c:749 trace: start_command: /bin/sh -c 'echo $* "$@"' 'echo $*' foo
Prior changes have made the documentation around the internals of the
alias command execution clearer, but I have still found this detailed
view of the aliased command being run helpful for debugging purposes.
A test case is added to ensure the full command output is present in
the execution flow.
