@sortas inserts unwanted space

Folks,


consider the following example.

======================================================================

\input texinfo.tex

@findex @sortas{foo} foo
@findex foobar
text

@printindex fn

@bye

======================================================================

Attached you can find the tex output using texinfo.tex from
2019-02-16.14 and 2020-05-22.11; as you can see, the @sortas command
no longer suppresses the insertion of a leading space.

The old `.fn` file looks like this:

  \entry{foo}{1}{\code {\ignorespaces  foo}}
  \entry{foobar}{1}{\code {foobar}}

The new `.fn` file is as follows:

  \entry{foo}{1}{\code { foo}}
  \entry{foobar}{1}{\code {foobar}}

This is a regression.
