Problem: File paths change from symlink to target path after :cd command
when editing files through symbolic links
Solution: Add "~" flag to 'cpoptions' to control symlink resolution.
When not included (default), symlinks are resolved maintaining
backward compatibility. When included, symlinks are preserved
providing the improved behavior. (glepnir)
