Not enough error information given if ]link.create # d:\tmp\dc fails if dc contains a subdirectory with a . in its name

**Describe the bug**
Not enough error information given if ]link.create # d:\tmp\dc fails if dc contains a subdirectory with a . in its name

**To Reproduce**
```cmd
cd d:\tmp
mkdir dc
cd dc
mkdir dir.2
cd dir.2
# create some .aplf files inside there.
```
in Dyalog 20.0.51678 with link 4.1.4
```
]link.create # d:\tmp\dc
Link Debug: ⎕SE.Link.Create: Linked: # ←→ "d:\tmp\dc"
ERRORS ENCOUNTERED:
6 import(s) failed:
"d:\tmp\dc\dir.2\Create.aplf"
"d:\tmp\dc\dir.2\Dir.aplf"
"d:\tmp\dc\dir.2\IO.aplf"
"d:\tmp\dc\dir.2\Sharing.aplf"
"d:\tmp\dc\dir.2\Tie.aplf"
"d:\tmp\dc\dir.2\∆dlt.aplf"
Linked: # ←→ "d:\tmp\dc"
ERRORS ENCOUNTERED:
6 import(s) failed:
"d:\tmp\dc\dir.2\Create.aplf"
"d:\tmp\dc\dir.2\Dir.aplf"
"d:\tmp\dc\dir.2\IO.aplf"
"d:\tmp\dc\dir.2\Sharing.aplf"
"d:\tmp\dc\dir.2\Tie.aplf"
"d:\tmp\dc\dir.2\∆dlt.aplf"
```
**Expected behaviour**
I would have liked more details about the error. Or some documentation about this limitation. I figured out it's the `.` in `dir.2` causing the problem through trial and error.

**Additional context**
A user was doing something like this:
```
]Tatin.InstallPackages Davin-FilePlus 'C:\tmp\mydir'
```
Then, I think they were doing something like:
```
]link.create # c:\tmp\mydir
```
and then getting errors.
