* config/tc-z80.c (z80_start_line_hook): Fix parsing of 'equ' or

'defl' in cases where the space between the keyword and the
expression has been scrubbed away.
Do not check whether a symbol is redefined with 'equ' here;
the function equals takes an argument indicating whether
redefinitions are allowed.
Only call LISTING_NEWLINE if needed, and then after the call to
bump_line_counters.
