Fix #186: allow continuation character in .conf files

This change makes it possible to use the standard continuation character
in .conf files.  For example:

    service [23456]     \
         log:stderr     \
         <!pid/foo>     \
         bar            \
         -- This is the bar service, it depends on foo # comment that's dropped

Notice the additional support for comments on .conf lines.  If you use
the comment character today you must change to escape it.  Like this:

    service :2 foo -- Foo \#2
