It could be annoying. Especially for the second case.
What about making the blrty.conf parser recognize quotes? Quoted
directives should be taken verbatim. So:
# foo's argument is a list of bar and baz
foo bar,baz
# foo's argument is a literal bar,baz
foo "bar,baz"
# and for the escaped case:
foo " \" "
In the last case, the argument to foo is a space, a quote and another
space. Such quoting rules are pretty common already.
