Package: grep
Version: 2.5.4-4
Severity: wishlist
File: /usr/share/man/man1/grep.1.gz
X-debbugs-cc: bug-grep@...

On the man page at:

   Context Line Control

**Please somehow mention at this place on the man page that Context will include
  blank lines in the fashion below, that one never expected.... mention
  the algorithm used. Thanks. Also mention how to just get a certain
  number of context lines, with no introspection about what the content
  of those lines are.**

       -A NUM, --after-context=NUM
              Print NUM lines of trailing context after matching lines.  Places a line containing a group separator (--)
              between  contiguous  groups  of  matches.  With the -o or --only-matching option, this has no effect and a
              warning is given.
