Looks like the behavior of subinword() has indeed changed in version
13. Since the local macro generate is an empty string, you are asking
to look for a non-existent token and replace it with a space. In other
words:
local vlist = "var1 var2 var3"
di subinword("`vlist'",""," ",.)
In version 12 and before, Stata displays an empty string. In version
13, Stata displays "var1 var2 var3". It does not make sense that a
missing token matches every word in vlist so I think that the new
behavior in version 13 makes more sense.
