Message-ID: <834ee95cd2fe919c7a5a2d3cc3d647cfdeebe9e6.1564603467.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.298.git.gitgitgadget@gmail.com>

From: Jeff Hostetler <jeffhost@microsoft.com>

Trim leading/trailing whitespace from the command line printed in the "start" message in the perf target format.

We use `sq_quote_argv_pretty()` to format the message and it adds a leading space to the output. Trim that.
