when merged more files are listed as changed

[Prabhakar S]

Greetings,

We have a scenario where for two releases we are having two repos and
sometimes when the two repos are merged, say repo_REL1 is merged to
repo_REL2 and for some conflicts with two or three files .

Once they are resolved and pushed, the notification email from hg shows ,
more number of files as changed than expected.

When i checked that , looks like it is generated using command below

hg diff -r <tip> -r <priortotip_notsure_ifitisexact prior_to_tip> | diffstat

Now the question is

1. Is the hg notification using the above approach to send the list of
modified files ?
2. Why is it showing more files as modified though only few files are
modified ?

Appreciate your help.

Regards,
S.Prabhakar
