# The changes to 'bugfix' are enough to show the bug: in fact, with only
|
|
# those changes, it's a very noisy crash ("RuntimeError: nothing
|
|
# committed after transplant"). But if we modify a second file in the
|
|
# transplanted changesets, the bug is much more subtle: transplant
|
|
# silently drops the second change to 'bugfix' on the floor, and we only
|
|
# see it when we run 'hg status' after transplanting. Subtle data loss
|
|
# bugs are worse than crashes, so reproduce the subtle case here.
