[hackers] [sbase][PATCH] sleep: Support omitted 0 before ., and . without trailing digits.

From: Mattias Andrée <maandree_AT_kth.se>
Date: Sat, 26 Mar 2016 19:02:23 +0100

That is, you can write for example .1 instead of 0.1,
or 1. instead of 1.0. The parsing is not strict, so can
also type . instead of 0.
