item calculated and space in key

[dakol]

It seems space are not allowed in key used in a calculated item:

works:
100*last("vfs.fs.size[/,free]")/last("vfs.fs.size[/,total]")

does not work (space before "free"):

100*last("vfs.fs.size[/, free]")/last("vfs.fs.size[/,total]")

log:
Can not evaluate function [last()]: item [hostname:vfs.fs.size[/, free]] not found

nobody uses space in Item Key parameters ?

But there are cases when space is needed:

- If a mountpoint contains a space (yes it is evil but can happen)
- If you use Zapcat to monitor your JEE server and need to get JVM Memory Usage:
jmx[java.lang:type=MemoryPool,name=Code Cache][Usage.used]]
jmx[java.lang:type=MemoryPool,name=CMS Perm Gen][Usage.used]]
etc...

So it would be great to be allowed to use space in calculated items
