I didn't want to be _that_ restrictive. I wanted to implement this: 1) the string can contain only characters -.a-zA-Z_0-9/ 2) the first character is not / If you want to forbid "-dir", you should perhaps also forbid "./-dir". So we'd probably get: ^\(\.\.?/+\|[a-zA-Z_0-9][-.a-zA-Z_0-9/]*/*\)+$ (Yes, I think path of ../../build-aux can make sense, if the configure belongs to a subpackage.) Which regexp would you pick?
