Regarding the mysterious "est hidden scalar" line, I am not sure what
that is but it appears verbatim in Stata 12.0's xtreg_fe.ado (in the
Stata12/ado/base/x folder, v1.8.3). It does not appear in Stata 11.2's
xtreg_fe.ado (in the Stata11/ado/update/x folder, v1.7.7), so it
appears to be something new to Stata 12.
You are right. Note that most of xtreg_fe.ado is run under version
control, specifically version 6. It includes several "est" commands
that look to me like they should be "ereturn" commands, or at least
they would be ereturn commands if the code was being written today.
Ergo, I am guessing that sometime after version 6 (I'm guessing Stata
8), the syntax of est was changed and various options were replaced
by ereturn. The "hidden" was probably added in v. 12 because some
values can now be "hidden", i.e. maybe this is a weird hybrid of old
and new syntax. I don't know if that helps you any, but that is my
guess as to why the code seems mysterious.
