Patch: Regular expression support for convert extension's 'filemap' option.

[Mads Kiilerich]

  I just posted a patch that tries to make the documentation in this 
area more clear. Feel free to improve so we know what we have before we 
even consider changing it.

And:

That would make it harder to detect ambiguous include/excludes and to 
control the precedence. How would you do that while staying 
("sufficiently") backward compatible?

While we are discussing this area: If we support regexp in 
include/exclude then it is a reasonable expectation that we also do it 
in rename, with proper use of references to matching groups...
