Nitpicking: those should be "Link" tags, as explained in
'Documentation/process/submitting-patches.rst' and
'Documentation/process/5.Posting.rst'? Never tried, but if you want to
make them footnote-style this should work according to the docs:
Link:
https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/481 [1]
Link: https://bugzilla.redhat.com/show_bug.cgi?id=1868789 [2]
In anyone wonders why I care: there are internal and publicly used tools
and scripts out there that reply on proper "Link" tags. I don't known
how many, but there is at least one public tool I'm running that cares:
regzbot, my regression tracking bot, which I use to track Linux kernel
regressions and generate the regression reports sent to Linus. Proper
"Link:" tags allow the bot to automatically connect regression reports
with fixes being posted or applied to resolve the particular regression
-- which makes regression tracking a whole lot easier and feasible for
the Linux kernel. That's why it's a great help for me if people set
proper "Link" tags.
While at it, let me tell regzbot about this thread:
