Addendum 1.
If *.o files are not treated expendable, you would be forced to
"make clean" every time you switch between these two branches,
which is unacceptable.
Addendum 2.
There was an old wishlist item to introduce another class of
paths (in addition to the "tracked", "untracked" and "ignored")
that are "ignored-but-precious". Then "*.o" would still be
expendable while a directory that must become a regular file
with "ignored-but-precious" files in it would prevent switching
from branch 'side' to 'master' in the illustration in the
previous message in order to keep that "ignored-but-precious"
file.
But nobody needed such a feature badly enough to step up and
implement it.
