Cut & Paste '~\.julia\dev' folder to a Windows MyDocuments folder

[johntrinder]

I have cut&pasted the '~.julia\dev' folder on the C: drive into Windows10 'MyDocuments' so that I can perform a daily synchronized backup of any changes.
To accommodate this I added the following line to my 'startup.jl' file:
pushfirst!(DEPOT_PATH, "D:\My Documents\JULIA\LIBRARY")

Now, when I create a package using (@v1.5) pkg> dev .
I get the following error report:

[ Info: Resolving package identifier . as a directory at D:\My Documents\JULIA\LIBRARY\dev\MyExtraTwo\.
Path . exists and looks like the correct package. Using existing path.
Resolving package versions...
ERROR: expected package MyExtraTwo [4fbb7824] to exist at path C:\D:\My Documents\JULIA\LIBRARY\dev\MyExtraTwo

As can be seen 'C:' is prepended to the '~\dev\MyExtraTwo' path; so presumably this is a bug.

Should be fixed in 1.6 (by #38259).
