Parenthesis should not require whitespace around them

[srtlg]

For compatibility with AVRASМ2 аn expression with a parenthesis around should not require to be separated via whitespace from the previous token

.device atmega168
.macro DEST
        .dw @0
.endmacro
nop
KEYLOOP:
        DEST(KEYLOOP)
