A funnily inconsistent behavior of int and float

[Lie]

I've noticed some oddly inconsistent behavior with int and float:

Python 2.5.1 (r251:54863, Mar  7 2008, 03:39:23)
[GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2
>>> int('-          345')
-345

works, but

>>> float('-       345.083')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for float(): -       345.083

The problem seems to be that float can't accept spaces between the
sign and the number while int can. Possibly caused by some missing
regex statement. Minor and harmless (most of the time), but should be
made known.
