Skip line continuation when it is a comment

Currently commented lines ending in the backslash character will be
concatenated with the following line.

```
 # with this comment \
exec swaynag -m 'will not run'
```

This change modifies `getline_with_cont` to stop reading when the
initial character is a '#'.
