least one whitespace character before them in order for them to be recognized
as a part of the multi-line parameter.
### Sizes
Where _specifically noted_, a number denoting a size can be suffixed by a subset of
the IEC binary prefixes or the SI prefixes. In the former case the number will be
interpreted as a certain multiple of 1024 and in the latter case as a certain multiple
of 1000. The supported IEC binary suffixes are `Ki`, `Mi`, `Gi` and `Ti` and the
supported SI suffixes are `k`, `M`, `G` and `T`. In both cases, the matching is
case insensitive.
For instance, the following entries
```
max_size=1099511628000
max_size=1073741824Ki
max_size=1048576Mi
max_size=1024Gi
max_size=1Ti
```
are equivalent, as are the following
```
max_size=1000000000000
max_size=1000000000k
max_size=1000000M
max_size=1000G
max_size=1T
```
