Avoid re-writing files unnecessarily in src/tools/copyright.pl.
The existing coding resulted in touching every copyright-containingfile in the tree, even if it was already up to date. That doesn'tmatter much for the annual run, but it's an annoyance if you tryto use the script for mop-up at the close of a devel cycle, asI just did.Discussion:https://postgr.es/m/266030.1649685473@sss.pgh.pa.us
