23.0.60; (minor) minibuffer file-name completion issue for files containing $

[Tim Van Holder]

Files present on the system:
 /foo/$blah.xyzzy
 /foo/$blah.quux

When pressing TAB twice to get completions for "/foo/$b", I noticed that
the fact that the $ gets escaped in the minibuffer seems to cause the
wrong letter to be highlighted in the *Completions* buffer (i.e. the 'y'
and 'u' are highlighted, respectively, instead of the 'x' and 'q',
respectively).
