Re: RFC: Change whatchanged to report changes from merges by default?

[Mark Burton <markb@ordern.com>]

Hi,

On further studying, I see that 1aec7917dc (git log: don't do merge
diffs by default) makes git log only show the log message by default
for merges. OK, no problem with that. 

However, in my mind, whatchanged is misleading when it doesn't output
anything (by default) for merges because, in my mind, that implies that
nothing has changed when, in fact, whole heaps of stuff could have been
merged in. So, if you forget to add the -m option, whatchanged will silently
ignore all the merged stuff and leave the poor user in the dark.

So, if changing the default behaviour is acceptable, I still think it would
be better if ignore_merges is set to 0 in cmd_whatchanged() but I guess an
alternative would be to set always_show_header, instead.

Any thoughts?

Cheers,

Mark
