Subject: [PATCH] option: accept 'sparse -U ...'
Date: Wed, 22 Jul 2020 23:28:04 +0200 [thread overview]
Message-ID: <20200722212804.36493-1-luc.vanoostenryck@gmail.com> (raw)
The '-D' flag was fixed to accept whitespace before the argument
but the '-U' flag wasn't. So, fix this now.
Fixes: 7f1011b311e9329f53d73f88de495ea64071eb77
