Hello

For the trunk ark, I realized some time ago that there is a lot of duplicate 
code between the RAR and 7zip plugin in Ark. The reason is that they are both 
formats controlled through command-line applications, so the solution was 
clear: make a common class for command-line-based archive formats, and use it 
for both of the formats (and any other formats one might want to try it out 
with).

And I'm wondering, is it possible to implement this plugin in trunk, and then 
backport it for 4.2.x once it is safe enough? For the user there would be no 
change, as it will still use the same desktop file, and the plugin would still 
use the same interface, only the implementation would be rewritten to use 
another superclass. I would off course also have to add this particular 
superclass into libkerfuffle (the weirdly named library where all the 
extraction logic of Ark is found).

Is this possible? Or will the current implementation have to be maintained 
until 4.3? (The problem is of course that I will be implementing this class 
either way, as it will allow very easily adding support for more command-line 
based formats quickly, but it would be a pain to keep bugfixing the old 4.2 
implementation for six months)
