Return statements with parameter enclosed in parentheses were modified and parentheses were removed. The whole change was scripted, here is how: List of files was obtained using this command: git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' | \ grep -e '\.[ch]$' -e '\.py$' Found files were modified with this command: sed -i -e \ 's_^\(.*\<return\)\s*(\(\([^()]*([^()]*)[^()]*\)*\))\s*\(;.*$\)_\1 \2\4_' \ -e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_' Then checked for nonsense. The whole command looks like this: git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' | \ grep -e '\.[ch]$' -e '\.py$' | xargs sed -i -e \ 's_^\(.*\<return\)\s*(\(\([^()]*([^()]*)[^()]*\)*\))\s*\(;.*$\)_\1 \2\4_' \ -e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_'
