remove: rewrite to be ~400x faster, bit more friendly old remove code called localrepo.changes for each file. was very expensive: $ hg --time rm arch>/dev/null Time: real 1066.120 secs (user 1014.450+0.000 sys 18.090+0.000) new code, same files: $ hg --time rm arch>/dev/null Time: real 2.770 secs (user 2.190+0.000 sys 0.580+0.000) also mention "-f" if not removing files. also allow "-f" to forget added files. make test a bit better.
