Convert all uses automatically, via these two commands:
git grep -l '\<exit *(1)' \
| grep -vEf .x-sc_prohibit_magic_number_exit \
| xargs --no-run-if-empty \
perl -pi -e 's/\b(exit ?)\(1\)/$1(EXIT_FAILURE)/'
git grep -l '\<exit *(0)' \
| grep -vEf .x-sc_prohibit_magic_number_exit \
| xargs --no-run-if-empty \
perl -pi -e 's/\b(exit ?)\(0\)/$1(EXIT_SUCCESS)/'
* .x-sc_prohibit_magic_number_exit: New file.
