If the 'buf' parameter is a non-0-length string, its contents will be edited. Previously, the initial value of 'buf' was ignored and the user entered its contents from scratch.
What is the purpose of this modification? Are you fixing a bug (which one?) or implementing an extension (which one) or what?
This change was necessary to add a new "editenv" command. This change allows the readline() function to edit a string instead of just enter one from scratch. In theory this feature could be used for other areas of U-Boot in the future, but at this point the only user of it would be the "editenv" command which I submitted a patch for. If the 'editenv' patch is rejected, I don't mind this one being rejected too.
+1 from me for new "editenv" :) -mike
