gas symbol_remove
If a symbol is at the start of the symbol chain then symbol_rootP
points at the symbol and symbol->x->previous is NULL. Testing either
condition is sufficient, there is no need to test both. Similarly for
the symbol at the end of the symbol chain.
I'm testing the previous/next pointer because it's most likely that
the symbol is not at the start/finish of the chain and thus we need to
use that pointer.
* symbols.c (symbol_remove): Tidy list handling.
(symbol_append, symbol_clone, symbol_insert): Likewise.
