patchbomb: respect HGPLAIN when piping --test output to PAGER
It makes easy to use `hg email --test` from another tool.
pager: fork and exec pager as parent process
With the pager as the child process instead of the parent process, the
termination of the parent Mercurial process can cause the terminal to return
before the pager exits. Inverting the relationship prevents that issue.
Platforms without fork() will continue to use util.popen().

merge: avoid to break the dirstate copy status on moved files

this will break the current copy state.
Note: only affect working directory merge, not branch merge.
