Improve the presentation of assembly blocks
Uncrustify indents
```
asm("foo"
HELLO "bar"
"wibble");
```
but we would like
```
asm("foo"
HELLO "bar"
"wibble");
```
Make "bar" an argument of the macro HELLO, which makes the indentation from
uncrustify match the semantics (everything should be aligned to the same
column).
