A regex doesn't change a string, but a substitution (one part of which
is a regex) does.

Can you insert spaces in either "FirstLast:" or "FirstMiddleLast:" with
the same substitution? That would depend on how you intend to recognize
the parts of the nname. You have said nothing about that.

Here is a substitution that inserts a space whereever a capital
letter immediately follows a lower-case one:

s/([[:lower:]])([[:upper:]])/$1 $2/g;

but that would mis-handle names like "McBarren".
