A user on irc noticed a missing backslash on one line in
update-gnulib.sh. This patch adds it.
Re-running update-gnulib.sh causes a few copyright notices to change.
Presumably these are from upstream gnulib and shouldn't be touched by
our yearly update. I've updated the script to account for this, but I
did not want to try testing it...
This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.
This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.
