FWIW, I am using SmartSVN on Windows. I believe a free version can do
all the basic manipulations and the full version is under $50. I am not
sure what you mean by "don't run very well into the MSYS+MinGW
environment" so perhaps SmartSVN has the same problem as the native svn
client and server you mentioned above.

Subversion knows about the end-of-line terminators and have knobs to
control them. I do not know whether they work in MSYS environment, but I
suspect they do.

$0.02,

Alex.
