pager: provide a default attend list

The default list includes commands which normally print large amounts of
text. This should be more user-friendly than paging all commands by default,
which can be confusing when the pager swallows input prompts (with, e.g.,
record, merge, HTTP/SSH authentication, etc.)

 You can also enable the pager only for certain commands using
-pager.attend::
+pager.attend. Below is the default list of commands to be paged::
 
   [pager]
-  attend = log
+  attend = annotate, cat, diff, export, glog, log, qdiff

+Setting pager.attend to an empty value will cause all commands to be
+paged.
 
 If pager.attend is present, pager.ignore will be ignored.
