indentation

[cooljeanius]

I disagree with the standard GNU indentation style. In my fork of gdb, I use the following args to indent in an indentation script:

additional_args="-as -cdw -ss -npcs -ncs -nbc -sar -nut -sob -gts -lps -i2 \
-di1 -l79 -bad -bap -nbbb -bls -blf -ppi1 -dj -cd0 -c1 -cp1 -ntac"

In this repo, they can be put in a Makefile variable named indent_args to override the setting in maint.mk (which is vendored in from gnulib). I need to find the proper place to do this, and handle fallout from places where reindenting with these args screws things up...
