I guess ERE would give us enough expressiveness to say "zero or one"
without relying on GNU extension.  Saying "Any whitespace" concisely
as "\s" would require PCRE (i.e. "grep -P") but because use of it is
optional, the best we could do is "[ ]" (in the [bracket]), one is
TAB and the other is SPACE).

But reading the message again, they are what the author of the patch
did to observe the current codebase, so I think being faithful to
what you did would be fine ;-)

In any case, thanks for cleaning it up.
