It seems that we have got different expectations on the editing work flow when
we discuss the following situation.

elfring@Sonne:~/Projekte> git --version && mkdir try && cd try && git init --quiet \
> && echo one > XYZ.h && git add . && git commit --message=check-in --quiet \
> && git checkout --quiet -b feature1 && echo two > XYZ.h \
> && git checkout --quiet master && git status
git version 1.7.0
# On branch master
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   XYZ.h
#
no changes added to commit (use "git add" and/or "git commit -a")

I would prefer to return to the unchanged work tree because I made an adjustment
for a source file with the intention that this update should only belong to the
new topic branch. The switch did not provide a clean state from my view.

I would create another topic branch before.

I can follow your view on convenience if the desired software maintenance is so
easy as in this example. I guess that it matters if only a simple branch switch
is needed or a corresponding content restore will also be required.

I would like to be more careful so that I do not want to mix changes by accident.

I imagine that stashing will help to split the collected changes for different
branch targets.
