Encode < as %3C and > as %3E in the linkmask. This gets used in the
"Link: ..." line written to commit messages. Reasoning is that at least
gnome-terminal will break the link at the < otherwise, making it harder
to right click and copy the link to paste it into another VM to open it
in a browser. That's how everybody does it, right?
Use %% instead of % for proper escaping with python's %-formatting.
Add a config, so the 'b4' tool from kernel tools can be used to get
Reviewed-By: etc. trailers into the commit messages. The tool only
supports lore.kernel.org, however I've written a proof of concept for
using this with SourceHut mailing lists too. See the wiki page for
