" Test 63: Suppressing error exceptions by :silent!. {{{1
"
" A :silent! command inside a :try/:endtry region suppresses the
" conversion of errors to an exception and the immediate abortion on
" error. When the commands executed by the :silent! themselves open
" a new :try/:endtry region, conversion of errors to exception and
" immediate abortion is switched on again - until the next :silent!
" etc. The :silent! has the effect of setting v:errmsg to the error
" message text (without displaying it) and continuing with the next
" script line.
"
" When a command triggering autocommands is executed by :silent!
