Subject: git-svn: support for funky branch and project names over HTTP(S)
X-Git-Tag: v1.5.3.8~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=f5530b8;p=git.git

git-svn: support for funky branch and project names over HTTP(S)

SVN requires that paths be URI-escaped for HTTP(S) repositories.
file:// and svn:// repositories do not need these rules.

Additionally, accessing individual paths inside repositories
(check_path() and get_log() do NOT require escapes to function
and in fact it breaks things).
