I've removed myself from commons.dev.
Why do I still get these messages?

Subject: [jira] Updated: (CLI-116) Allow to configure the width of the
first column on the HelperFormatter.print() method

Brian Egge updated CLI-116:
---------------------------

    Description: 
Just to suggest to allow the user to control the with of the first
column of the generated output from HelperFormatter.print() method, for
the option description.

Now this with is delimited by the longest option and some times it is
not the best solution, because the width of the second column
(description) in order to fix the maximum length (default 80) has to be
short.

My suggestion is to give the possibility to the user to wrap the option
definition (first column), in case it is going to be longer to a given
value. This is useful for group options, for example something like
this:

-report (-r)
    -date|-list|-template|-param-names|-param-values|-format 
      -date (-d) date
      -list (-l)
      -template (-t) template [template ...]
      -param-names (-pNames) name [name ...]
      -param-values (-pValues) value [value ...]
      -format (-f) format [format ...]

so the description field will be started after the longest option
definition, at column position after: 

    -date|-list|-template|-param-names|-param-values|-format 

a better solution would be nevertheless to wrap also this line to a
given length, for example:

-report (-r)
    -date|-list|-template|-param-names
     |-param-values|-format 
      -date (-d) date
      -list (-l)
      -template (-t) template [template ...]
      -param-names (-pNames) name [name ...]
      -param-values (-pValues) value [value ...]
      -format (-f) format [format ...]

it is easy to see the line is wrapped because the indentation level, so
now the second column, that is the description, will come after the
-param-names option definition which is now the longest option
definition.

Thanks in advance,
