I made the change to not allow spaces in links a few months ago.  Most
recently, the change was from " \t\n" to "[:space:]" in the first part
of extended links, which is correct in itself, AFAICT.

Could you tell me why you need to have links with spaces in them?
What is that supposed to link to?  If I can understand why you need
that functionality, I'll put it back in.

Spaces aren't normally allowed in most kinds of links, from what I
understand.  The only time a space has been needed in a link so far
has been links to Info nodes, but those can be escaped with "%20" and
are done so by default when you create a task from an Info node.

So by not allowing spaces in the first part of extended links, it is
supposed to help someone who accidentally puts a space in the wrong
place by refusing to display it as a link.
