Not exactly. If the local file (or files) only contain "synaptics", the matching
file names will be passed to Yum, and it won't find packages with that name:

  $ touch foo-synaptics-fubared
  $ yum list *synaptics*
  Error: No matching Packages to list

This is the same as running "yum list foo-synaptics-fubared". There is
only one special case, a local file with the name "synaptics", which
_is_ a package name:

Therefore it only finds package "synaptics".
