[jira] Commented: (CLI-137) Change of behaviour 1.0 -> 1.1

["Steve Ogden (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CLI-137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12571477#action_12571477 ] 

Steve Ogden commented on CLI-137:
---------------------------------

This broke us as well.  We expected that an option may be repeated multiple times on the command line with the same semantics.  For example, assume that -F takes only one arg.  This was true in CLI 1.0 for every occurrence of -F.  We didn't want every arg to be lumped into a general -F bucket.  This allowed us to do this in 1.0:

   trial -F 1 -F 2 -F 3 file1 file2

and have the output be:

   -F 1
   -F 2
   -F 3
   file1 file2

not as it is now in 1.1:

   -F 1
   -F 2
   -F 3 file1 file2
