test-histedit: $TESTTMP quoting fixes for Windows Without this, C:\path\to\test is converted into C:pathtotest. Since $TESTTMP appears in output, seems to work in some places without quotes, and is also used within a larger quote block (see test-rebase-collapse.t, ~line 160), I'm not sure what a check-code rule would look like (or even if it is feasible).
