Title: Edge case in [file normalize]?

Description:

As reported in this Stack Overflow question, it looks like there's an evil edge case that's gone wrong in file normalize.

Directory structure setup:

/tmp/fileA.txt
/tmp/sidedir/fileA.txt
/tmp/subdir/fileA.txt
/tmp/subdir/sidedir_link -> /tmp/sidedir
Problem trace:
wish% file normalize sidedir_link/fileA.txt
/tmp/sidedir/fileA.txt
wish% ::utils::realpath sidedir_link/fileA.txt
/tmp/sidedir/fileA.txt
wish% file normalize sidedir_link/../fileA.txt
/tmp/subdir/fileA.txt
wish% ::utils::realpath sidedir_link/../fileA.txt
/tmp/fileA.txt
Note: The difference is /tmp/subdir/fileA.txt versus /tmp/fileA.txt.”
It's reportedly an issue with both 8.4.9 and 8.6.1 so I expect it to be present in all other 8.4, 8.5 and 8.6 versions.

This is probably a Dup.

If it were easy to fix (or to define what
functioning is properly defined as "fixed"),
it would be done by now.
