Subject: fake_outputs: Allow designating a fake output as primary
X-Git-Tag: 4.15~72^2~1
X-Git-Url: https://git.sur5r.net/?p=i3%2Fi3;a=commitdiff_plain;h=caae4db0bc6516b08a2f138c5845c34053e50947

fake_outputs: Allow designating a fake output as primary

Allow appending 'P' to the fake output specification to set the
created output's "primary" flag, to allow writing test cases that
depend on the presence of a primary output.
