Description of problem:

After running 'man dig' one is presented with something like this:

....
    .PP The IN and CH class names overlap with the IN and CH top level domain
names. Either use the -t and -c options to specify the type and class, use the
-q the specify the domain name, or use "IN." and "CH." when looking up these
top level domains.
  .SH "SIMPLE USAGE"
    .PP A typical invocation of dig looks like:
....

and later on the page even worse:
.....
                                     .PP -c class
                                          Set the query class. The default
                                   class is IN; other classes are HS for
                                   Hesiod records or CH for Chaosnet records.
                                         .RE
                                         .PP -f file
                                              Batch mode: dig reads a list of
                                       lookup requests
.....
and so on, and so on ....

The issue is that numerous roff directives in this file do not start on the left margin but are preceded by various amounts of a white space.  Running dig.1 through the following command:

   sed -i 's/^[[:space:]][[:space:]]*\././' dig.1

fixes this headache.

Version-Release number of selected component (if applicable):
bind-9.10.4-3.P5.fc25

Additional info:

Among various manpages from this package dig.1 is the only one produced by: "DocBook XSL Stylesheets v1.79.1".  No idea if this is relevant but other manpages from bind-utils do not suffer from this affliction.
