copies: inline a variable that's used only once By inlining it, we also avoid calculating the value when "if of in seen" is false (probably not significant). Differential Revision: https://phab.mercurial-scm.org/D4831

bundlerepo: remove a variable alias "parentrepo" and "repo" were the same thing and I don't see much reason for it (unionrepo has similar structure and a similar alias but there are two repos there so at least it makes a little more sense there).
