Subject: Fix: ensure a newline is printed before exit on client destroy
X-Git-Tag: v2.12.0-rc1~528
X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=f16edb77944b361ceaef95bf290d634231cf55b1

Fix: ensure a newline is printed before exit on client destroy

Errors encountered during the destruction of a session can cause
the `lttng` client to exit after having printed the
'Waiting for destruction of session ...' message without printing
a newline. This causes the user's prompt to reappear after the
message and not on a new line.
