Description

In the latest patchlevel versions of the ruby_1_8_6 branch, the File.extname method stopped returning empty Strings for files starting with a dot:

Latest version of the ruby_1_8 branch:
File.extname(".profile") # => ""

Latest version of the ruby_1_8_7 branch:
File.extname(".profile") # => ""

Latest version of the ruby_1_8_6 branch:
File.extname(".profile") # => ".profile"

This is a Ruby 1.8.7 feature so who changed its behavior is 1.8.7,
rather than 1.8.6.

That is definately a bug, as earlier Ruby 1.8.6 patchlevels showed
exactly the same behaviour as 1.8.7:

VERSION = 1.8.6-p111:

irb(main):001:0> File.extname(".profile")
=> ""

VERSION = 1.8.6-p114

irb(main):001:0> File.extname(".profile")
=> ""

VERSION = 1.8.6-p166

irb(main):001:0> File.extname(".profile")
=> ""

VERSION = 1.8.6-p222

irb(main):001:0> File.extname(".profile")
=> ".profile"

VERSION = 1.8.7-p17

irb(main):001:0> File.extname(".profile")
=> ""

VERSION = 1.8.7-p7

irb(main):001:0> File.extname(".profile")
=> ""

VERSION = 1.8.7

irb(main):001:0> File.extname(".profile")
=> ""

Ah, sorry I was wrong.

I've backported corresponding patch from 1.8 branch.  Thank you pointing this out.
