I typed "c:\bin\" in the minibuffer and hit tab. After hitting tab, the
minibuffer contained "c:/usr/bin", with point at the end.

Now that you mention it, I do see that the leading "c:" in the minibuffer
ishighlighted. That explains why we're substituting "c:/usr/bin" and not "/usr/bin".

Not all paths I want to catch are absolute, so looking for a drive letter won't
catch everything. Even "absolute" paths can be drive-letter-relative and begin
with a simple backslash. Looking for a backslash is convenient because no
legitimate Cygwin path contains one.

Cygwin interprets backslashes as separators.
