Take long option names for -A (--after-context), -B (--before-context)
and -C (--context) from GNU grep and add a similar long option name
for -W (--function-context).
Why not just add --context=function? Then when I want --context=indent
to give context based on the indent-level, it is an intuitive extension
of the existing options. (Of course, --context=<number> would still do
exactly what it does now.)
