From: Johannes Schindelin <johannes.schindelin@xxxxxx> Previously, we waited for the child process to be finished in every failing code path as well as at the end of the function `show_range_diff()`. However, we do not need to wait that long. Directly after reading the output of the child process, we can wrap up the child process. This also has the advantage that we don't do a bunch of unnecessary work in case `finish_command()` returns with an error anyway.
