           Summary: Doesn't play well with file symlinks
           Product: kompare
           Version: 4.0.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kompare-devel at kde.org
        ReportedBy: ggrothau at gmail.com


Version:           4.0.0 (using KDE 4.4.5) 
OS:                Linux

Diff a file which is a symlink, edit that file (such as applying changes), and
then save the file.  Kompare will replace (delete, add) the file rather than
modify it, which deletes the symlink and adds a new real file.  It would be
preferred if the destination of the symlink was updated and the symlink
preserved. 

Reproducible: Always

Steps to Reproduce:
Diff a file which is a symlink, edit that file (such as applying changes), and
then save the file.

Actual Results:  
Kompare will replace (delete, add) the file.

Expected Results:  
Kompare will modify the file.

This is a bit of a corner case, but was encountered in the following scenario: 
Kompare is used within a script to process a set of files produced by another
program (ie: git diff) but the user doesn't want to have kompare process all of
the unchanged files in the same subtree.  That script can create a temporary
tree with just the changed files as symlinks for kompare to look at.
