histedit: use base for computing renames when folding (issue3729)
When a file was renamed in the very first changeset being histedited,
the rename was not detected. Consider a history like this:
0 base: add a.txt
1 first: rename a.txt to b.txt
2 last: edit b.txt
When 1 and 2 are edited, copies.pathcopies(first, last) correctly
returns that nothing was renamed. We must instead use
copies.pathcopies(first, last) to detect the initial rename.
Test histedit extention: Fold commands
======================================
This test file is dedicated to testing the fold command in non conflicting
case.

folding and creating no new change doesn't break:
-------------------------------------------------
folded content is dropped during a merge. The folded commit should properly disapear.

dropped revision.
