fname parsed incorrectly - unnamed buffers

[j5shi]

Sometimes the fname will be parsed as (I've no idea why it happens in that way):

C:\Program Files (x86)\vim\[18*No Name]

So the result of regex matchstr(fname, '\d\+') will be 86, which is obviously incorrect.

You can use str2nr(matchstr(matchstr(fname, '\[\d\+\*No Name\]$'), '\d\+')) to solve it.
