is colored as a parameter, not a command. Promote this from a tok_string
to a symbol_argument in the grammar too.

b520a03c57 Prefer swap() member function to std::swap. We were hitting the 
inefficient generic std::swap for some derived types.

ad6367018b Excise use of parser_t's error() functionality. Thread a 
parse_error_list_t through all of the expand functions, enabling them to
report errors more directly. Improve aspects of error reporting for
expansion failures.

1fbf633817 Reimplement exec parsing. Instead of special-casing exec as a command, 
promote it to a decoration (like 'command' or 'builtin'). This makes tab
completion and syntax highlighting treat exec's first argument as a
command and is otherwise a nice simplification. Fixes #1300

0e9d159bc2 Improvements to error reporting. In particular, we now append a newline 
in reader_shell_test, so that there's always a statement terminator.
Otherwise commands like 'echo |' would not be considered an error (just
incomplete).
