Overwriting files and not replacing packages - (no Replaces)

[Mathieu Malaterre <malat@debian.org>]

Dear mentors,

I have uploaded CharLS 2.1.0+dfsg-7 with a single Breaks statement (no
Replaces statement):

$ cat d/control
...
Breaks: libdcmtk-dev (<< 3.6.4-2.1)

In this specific case I do not need 'Replaces:' (*), because
'libcharls.so' from libdcmtk-dev is not meant to be replaced by the
one shipped in libcharls-dev (2.1.0+dfsg-7) (this is not the normal
breaks+replaces pattern).

Is my understanding correct?
