A badly formatted .linkconfig file leads to a value error for Name when creating a link

[dyavc]

Describe the bug
A badly formatted .linkconfig file leads to a value error for Name when creating a link

To Reproduce
Steps to reproduce the behaviour:
copy the attached files.zip to a directory of your choice and unzip it to extract the files
rename badlinkconfig to .linkconfig

Start dyalog and set ⎕se.dirn to point at your directory:

⎕se.dirn←'c:/tmp/linktest'
⎕se.(opts←⎕NS'')
⎕se.opts ⎕SE.Link.Create # ⎕se.dirn
VALUE ERROR: Undefined name: Name

Expected behaviour
User expects a better error. The user writes,
"The root cause of the VALUE ERROR lies inside Link.Config.SetSourceFlags expecting "Name" to exists. This ought to be verified e.g., in Link.Config.ReadConfigFile and issue proper error message.

opts ⎕SE.Link.Create #(root,'src')

SetSourceFlags[5]

)si
⎕SE.Link.Config.SetSourceFlags[5]*
⎕SE.Link.Create[170]
"
