Trim whitespaces from a string?

[mbirth]

For some reason, Acer did store the manufacturer and product in my Acer Aspire One as:

Code:

"Acer      "
"Aspire one      "

And when outputting this to the screen, the added spaces look weird:

Code:

"Acer      Aspire one      boot menu"

I found several settings types which convert the data, e.g. uristring, hex, etc. ... but I didn't find a way to just trim the excessive spaces.

I found this discussion on the mailing list, but the mentioned trick doesn't work anymore and there's no other solution to the problem in that thread. There was also a proposal for a new "trim" command, but that's where the thread ended.

Is there a way to trim whitespaces?
