elmentary (watson): merge (named) branches and/or bookmarks

[Uwe Brauer]

Hi


Sorry for such an elementary question again, but bookmarks drive my
crazy.


I usually prefer named branches and the following works as expected:


hg init
echo feature > new.el
hg add new.el
hg commit -m feature1
echo offical2 >> new.el
hg commit -m feature2
echo feature3 >> new.el
hg commit -m feature3
hg branch exam
echo exam > exam.el
hg add exam.el
hg commit -m exam
echo exam2 >> exam.el
hg commit -m exam2
hg update default
hg merge exam

Now for some repos I have to use the hg-git plugin (since these repos are 
using git) so I have to use bookmarks instead of named branches. So I
thought the equivalent to the above would be

hg init
hg bookmark master
echo feature > new.el
hg add new.el
hg commit -m feature1
echo offical2 >> new.el
hg commit -m feature2
echo feature3 >> new.el
hg commit -m feature3
hg bookmark exam
echo exam > exam.el
hg add exam.el
hg commit -m exam
echo exam2 >> exam.el
hg commit -m exam2
hg update master
hg merge exam

But I obtain 

abort: nothing to merge
(use 'hg update' or check 'hg heads')

Sigh what is the problem here?
