Hi,

After upgrade GIT from 1.7.2.5-3.1 to 1.7.10.4-1+wheezy1 following error 
appear:

hooks were downloaded from:

My colleague did some research about that and it seems that this commit 
has stopped update hook working:

     Sanity-check config variable names

     Sanity-check config variable names when adding and retrieving them. 
  As a side
     effect code duplication between git_config_set_multivar and 
get_value (in
     builtin/config.c) was removed and the common functionality was 
placed in
     git_config_parse_key.

     This breaks a test in t1300 which used invalid section-less keys in 
the tests
     for "git -c". However, allowing such names there was useless, since 
there was
     no way to set them via config file, and no part of git actually 
tried to use
     section-less keys. This patch updates the test to use more 
realistic examples
     as well as adding its own test.
