Bizarre output from svnlite during ports update

[bob prohaska]

While updating /usr/ports on 11.0-PRERELEASE FreeBSD 11.0-PRERELEASE #0 r305394
the output of svnlite started out normally and then looked like this:

A    sysutils/e2fsprogs/files/patch-lib_ext2fs_unix__io.c

before returning to normal.

The connection was over ssh, it had been up for a week or so with
no indication of garbage or corruption (there is a wireless link
in the chain). 

Might this be indicative of a deeper problem?
