sh: Detect various additional errors in the parser.

Apart from detecting breakage earlier or at all, this also fixes a segfault
in the testsuite. The "handling" of the breakage left an invalid internal
representation in some cases.

Examples:
  echo a; do echo b
  echo `) echo a`
  echo `date; do do do`

Exp-run done by:	pav (with some other sh(1) changes)
