Sorry for the delay, slack stopped working with debian "oldstable"'s version of
chrome (big fullscreen "too old" tantrum page), and I went down a rathole of
asking #devuan IRC why a newer one wasn't in the backports repo, and they
forwarded me to the Debian guys who said Google's builds are too brittle to even
_try_ building chromium on anything but the newest release with all the current
compilers and libraries. So I have to do a major OS version update before I can
use slack on my laptop again, and confirming that took a while. (I miss static
binaries.)

Anyway, I broke this adding the --wildcard stuff, commit 24133d5e23d7 should fix
it. Sorry about that...
