It looks like that this method can be made const I think.

I also did ont pay too close attention in the previous patch, but it
looks like you use space indentation.  I think GNU standard[1] and GDB
codebase uses tab indentation (tab size of 8):

    The rest of this section gives our recommendations for other aspects of
    C formatting style, which is also the default style of the indent
    program in version 1.2 and newer. It corresponds to the options

    -nbad -bap -nbc -bbo -bl -bli2 -bls -ncdb -nce -cp1 -cs -di2
    -ndj -nfc1 -nfca -hnl -i2 -ip5 -lp -pcs -psl -nsc -nsob

This way to tell things is not super informative in itself.  Depending
on the text editor you use, there might be a configuration option to
help you automate this.

I will not point it out in every place in the patch, but there are
multiple instances where your changes lead to a indentation change (i.e.
replace 1 tab with 8 spaces).  This should be avoided.

2021 will most probably need to become 2022 (and same goes for other new
files as well).

Here you change the indentation from the previous patch.  This change
should probably be moved to it.

I understand that this is tedious to change and am sorry for that.

Best,
Lancelot.
