Danny Faught 01aee1a859 improve short description 
* The short description used to say that until commit
  aac7d76047 from 2014. It appears that
  it was changed by mistake in that commit to something less readable.

* With the message "use -print0/-0" we were confused and introduced a
  bug in our code because we didn't understand what to do with the
  "-0".

* SC2011 (source
  c9e27c2470/src/ShellCheck/Analytics.hs (L591))
  uses that exact warning message, we copied it from there.

Peter Oliver 128351f5ef Permit colon after exec 
ShellCheck throws warning SC2093 when a script contains commands that could never be executed because they are after an `exec`.  Command `:` does nothing, so add it to the list of commands that don’t trigger this warning.

Rune Juhl Jacobsen 3a118246ef
Fix bug in 2126 when using after/before flags with grep 
Using `--after-context`/`-A` or `--before-context`/`-B` would give a warning
recommending the user to use `grep -c`, even though that would give a different
result than using `grep | wc -l`:

```fundamental
$ echo -e "1\n2\n3" | grep -cA 3 1
1
$ echo -e "1\n2\n3" | grep -A 3 1 | wc -l
3
```
