[PATCH 2 of 2] histedit: use base for computing renames when folding (issue3729)

[Simon He.]

It looks like the description is not correct. The 2nd time “copies.pathcopies(first, last)” should probably be “copies.pathcopies(BASE, last)” (in lowercase of course). This is at least what I understand from the title and the diff.

Greetings,
