Some more explanation might be wished.

First off, there is a tacit assumption here that the name has been
trimmed of leading and trailing spaces.

Use -trim()- first, therefore.

Second, the logic is that if the last word is a single character, then
the previous character is a space. So we look for a space as the
penultimate (one before last) character of a name.

Note that

replace fullname = subinstr(substr(fullname, -2, 2), "", 1)  if
substr(fullname, -2, 1) == " "

is _not_ the way to do it as can be seen from

. local foo "John Anthony A"

. di subinstr("`foo'", substr("`foo'", -2, 2), "", 1)
Johnnthony A
