This probably works, however, even better is to check whether the
"location" starts with "file://" and then look there. Maybe one can
just call the function recursively just with another "file"
parameter (must "file" exist actually?). If "location" doesn't
start with "file://", do the fallback.
The Bazaar documentation explicitly says that lightweight checkouts
should be done only locally. For example, you can use them to
switch efficiently between locally stored branches. Therefore, one
can expect "file://" in most cases indeed.
I use to have many files open (40+), and when I start Emacs, I can
see a significant CPU usage of bzr processes now, thus my concern.
Tschö,
Torsten.
