Sign-off?

The above explanation sounds sensible.

Thanks.

[PATCH v6 07/10] connect.c: Corner case for IPv6

2013-11-21 Thread Torsten Bögershausen
Commit faea9ccbadf75128 introduced "user-relative paths":
"ssh://host.xz/~junio/repo" is the same as "host.xz:~junio/repo".

Commit 356bece0a27258181 "Support [address] in URLs" introduced a regression:
When an URL like "[::1]:/~repo" is used, the replacement of "/~"
with "~" was enabled for IPv6 host names, and "[::1]:/~repo" is
converted into "[::1]:~repo".

Solution:
Don't use "if (url != hostname)", but look at the separator instead.
Rename the variable "c" into separator.
