Skipping empty strings?

Is it possible to skip empty-on-purpose translation strings?

This is a standard Rails yaml file:

```
en:
number:
human:
decimal_units:
format: "%n %u"
units:
billion: Billion
million: Million
quadrillion: Quadrillion
thousand: Thousand
trillion: Trillion
unit: ''
format:
delimiter: ''
significant: true
strip_insignificant_zeros: true
storage_units:
format: "%n %u"
units:
byte:
one: Byte
other: Bytes
gb: GB
kb: KB
mb: MB
tb: TB
percentage:
format:
delimiter: ''
precision:
format:
delimiter: ''
```

A bit annoying needing to skip these every time, as well as always having a few "Strings needing actions"

There doesn't seem to be a Flag for this
