Bug#653750: According to the text, there should have been an indented line

[Regid Ichira]

  I think that the example is not ilustrative.  Is the indented line
apparent?

$ zgrep -B7 -A1 'aol.com:  spammer1 : spammer2 :' \
>        /usr/share/doc/exim4-base/spec.txt.gz

    If a local part that actually begins with an exclamation mark is required,
    it has to be specified using a regular expression. In lsearch files, an
    entry may be split over several lines by indenting the second and
    subsequent lines, but the separating colon must still be included at line
    breaks. White space surrounding the colons is ignored. For example:

    aol.com:  spammer1 : spammer2 : ^[0-9]+$ :
    spammer3 : spammer4

     aol.com:  spammer1 : spammer2 : ^[0-9]+$ :
-    spammer3 : spammer4

     As in all colon-separated lists in Exim, a colon can be included in an item
     by doubling.
