Subject: Better line parsing.

1. Explicitly remove comments.
2. A trailing backslash means the current line continues on the next line.

E.g.

    a \
      b \
      c

is a single line `a b c`.

This helps alleviate the fact that configuration lines can be very long,
whereas the *Custom key mappings* input is quite narrow.

TODO: We should use the same line parser in the custom-search-engines
input.
