Hi,

Setting GIT_SSH when using "git svn clone svn+ssh://..." does not

This is now in past tense, no?

Yes... this is all in the past tense now :) ... should be "did not override the default ssh". I'll fix it if I have to resend the patch for a different reason.

This is a change from before... I do not know if it is a good one, as SVN_SSH could be defined differently by the user, no? In that case, the user was most likely using the correct amount of backslashes...
Dscho, The *correct* amount of backslashes is 1 (per dir) - same as used with GIT_SSH. If the user has set SVN_SSH but not GIT_SSH (most likely without escaping \), then fixing up SVN_SSH for use with git-svn is not a bad thing.

I did this change to retain existing behavior (using SVN_SSH to override) even when user doesn't know the \\ quirk - or if the user has set it for some other non-msys version of svn.
So maybe it was correct to make this dependent on "if defined $ENV{GIT_SSH}", and maybe it should be dependent on "&& !defined $ENV{SVN_SSH}" as well...

Ciao,
Dscho
