branch: master
commit e8cedbfcd1a10f8b03d59f109e2ac86f0411be04

Commit: Basil L. Contovounesios <contovob@tcd.ie>

    Fix recent "erts files" additions in ERT manual
    
    * doc/misc/ert.texi (erts files): Indent examples with spaces rather
    than tabs, since Texinfo treats tab characters as a single space;
    see (info "(texinfo) @example").  Fix typos/thinkos.
