Log Message:
indent: remove redundant comments, remove punctuation from debug log

The comment about 'null stmt' between braces probably meant 'no
statements between braces'.

The comments at psym_switch_expr only repeated what the code says or had
been outdated 29 years ago already since opt.case_indent does not have
to be 'one level down'.

In the debug log, the quotes around the symbol names are not necessary
after a ':'. The parse stack also does not need this much punctuation.

Reducing a do-while loop to nothing instead of a statement saves a few
CPU cycles. It works because after each lbrace, a stmt is pushed to the
parser stack. This stmt can only ever be reduced to a stmt_list but
never be removed.
