Subject: If someone provides a --prefix that ends with slash, strip the slash.
X-Git-Tag: v1.7.11-rc0~176^2~34
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=6f2012cdc021f6b47ed19bc7fe64159ce9eeda8a;p=git.git

If someone provides a --prefix that ends with slash, strip the slash.

Prefixes that differ only in the trailing slash should be considered
identical.

Also update the test to check that this works.
