[patch] pkg_add cosmetic issue when asking for dependency

[Carlin Bingham]

If pkg_add asks for a dependency immediately the "No change in quirks"
text isn't cleared, and the "Ambiguous..." message prints on the same 
line.


Before:

$ pkg_add git
quirks-2.26 signed on 2014-10-23T16:24:44Z
|No change in quirks-2.26Ambiguous: choose dependency for git-2.1.2:
  a       0: rsync-3.1.1
          1: rsync-3.1.1-iconv



After:

$ pkg_add git
quirks-2.26 signed on 2014-10-23T16:24:44Z
Ambiguous: choose dependency for git-2.1.2:
  a       0: rsync-3.1.1
          1: rsync-3.1.1-iconv
