Description

When t exists in the current directory under the drive C:,

File.realpath("c:t") #=> No such file or directory @ realpath_rec - c:/t (Errno::ENOENT)

whereas File.expand_path returns Dir.pwd + "/t".

[Bug #14640] Fix File.realpath with a drive-relative path

A drive letter without a following separator ("c:t") means a path relative to the current directory of that drive, as File.absolute_path interprets it, not the absolute path "c:/t". A drive-relative basedir is read the same way, "~" stays literal since realpath does not expand home directories, and US-ASCII or ASCII-8BIT input is expanded in the filesystem encoding so that a non-ASCII current directory does not come back as "?".
