git-svn fetch doesn't like spaces in branch names

mini:TextMateBundles mjc$ git-svn fetch
Found possible branch point: http://macromates.com/svn/Bundles/trunk/Tools/Dialog 
  PlugIn => http://macromates.com/svn/Bundles/branches/Dialog PlugIn  
Completion Menu, 8089
Initializing parent: Dialog PlugIn Completion Menu@8089
Bad URL passed to RA layer: Malformed URL for repository at /opt/local/ 
bin/git-svn line 1607

looks like that might need to be %20 ?

Hacky, but it works.

You don't need "[" and "]".

You don't even need the "(" and ")"

$branch_from =~ s@\s@sprintf("%%%02X", ord($&))@seg;

But I think it'd be better to fix this properly.  I guess some people  
use branch names with accentuated characters such as é è ü whatever.   
What about this instead (untested):

$branch_from =~ s@[^\w\d_]@sprintf("%%%02X", ord($&))@seg;

Otherwise there are various existing Perl modules such as http:// 
search.cpan.org/dist/URI/URI/Escape.pm but this seems overkill / not  
portable (unless we distribute these files along with Git).

Cheers,

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

[Eric Wong]

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).
