Hi Mark,
thanks for your advice.
I just don't have an example on hand. Perhaps it only got a wrong habit,
because of some weird experiences in old days.

Do you have an example of error messages which are returned with such
'mixed' paths in them?

Unfortunately, this is a general issue. Quite often the values you might
need to use internally to actually run code will be different from those
which users might expect. So some 'formatting for display' is always
generally required in user-facing messages.

A similar situation to this is that of locale-specific number formatting
(which, admittedly, LiveCode doesn't currently support).

In the UK, we use '.' as the decimal separator; in many European countries
it is ','. It is easy to see why you need a fixed way to represent numbers
when running them through script - i.e. using '.':
   put item 2 of "1.05,2.05,3.05"

If you used the user-formatted version of numbers you might end up with
trying to do this:
   put item 2 of "1,05,2,05,3,05"

Which would, obviously, give you a completely different result! 
Filepaths are no different to this, and the same runs for dates, currencies,

Warmest Regards,
