Subject svn commit: r1358101 - /subversion/trunk/subversion/svn/file-merge.c
Date Fri, 06 Jul 2012 10:06:38 GMT
Author: stsp
Date: Fri Jul  6 10:06:38 2012
New Revision: 1358101

URL: http://svn.apache.org/viewvc?rev=1358101&view=rev
Log:
Cosmetic tweaks for the interactive merge tool side-by-side display.

* subversion/svn/file-merge.c
  (prepare_line_for_display): Always use the LINE_DISPLAY_WIDTH constant
    directly, rather than an intermediate local variable.
    Fix an off-by-one bug that prevented us from properly chopping newlines
    off lines that contain only a newline.
  (SEP_STRING): Adjust length of each segment to actual line display length.
  (merge_chunks): Stop displaying extra blanks to use as much screen estate
   as possible.
