chg: exec pager in child process
Before this patch, chg uses the old pager behavior (pre 369741ef7253), which
executes pager in the main process. The user will see the exit code of the
pager, instead of the hg command.
Like 369741ef7253, this patch fixes the behavior by executing the pager in
the child process, and wait for it at the end of the main process.
