strip: access bookmark before getting a reference to changelog
Bookmark access might invalidate the current changelog (to make sure both are in
a reasonable synchronisation state). So we should grab the reference to
changelog after we access bookmark. Otherwise we risk using a dead object for
the whole strip process.
(note: this dead object business probably requires a new layers of checking)
#require clang-format test-repo
$ . "$TESTDIR/helpers-testrepo.sh"
$ cd "$TESTDIR"/..
$ for f in `testrepohg files 'set:(**.c or **.cc or **.h) and not "listfile:contrib/clang-format-ignorelist"'` ; do
> clang-format --style file $f > $f.formatted
> cmp $f $f.formatted || diff -u $f $f.formatted
> rm $f.formatted
