Subject: [PATCH] CTest.UpdateHG: Fix repo URL for leading slash

Use "file:///..." instead of "file:////..." when the file system path
starts in a slash.  Commit 0916cc88 (CTest.UpdateHG: Fix repo URL for
local filesystem, 2012-03-02) added a third slash after "file://"
unconditionally.  This worked for many file systems but not on Cygwin
where "file:////cygdrive/..." looks like "file://" followed by a network
file path "//cygdrive/...".  Add the slash only if the file system path
does not already start with one.
