Hi Arnout.
Yes, i couldn't figure out a cleaner way to do this, continues below...

I could have probed the timeconst.pl file presence and relevancy (if it 
contains defined(@array)...), but then a dry-run patch does that for me 
just fine with the proper parameters.
Yes, that's the reason for APPLY_PATCHES, however since it's already 
there why bother duplicating code?
Also thought of extending apply-patches.sh to add an option for 
try-do/discard, but i believe it's a double-edged sword and not worth it 
quite yet.

Possibly, let's hear other people thoughts on this.
