As reported [1], 'git maintenance unregister' fails when a repository is
located in a directory with regex glob characters.

The discussed solution was to modify 'git config' to specify that the
'value_regex' argument should be treated as an exact string match. This is
the primary change in this series, with an additional patch at the end to
make 'git maintenance [un]register' use this option, when necessary.

Updates in V2
=============

 * Updated the test structure for the new tests in t1300-config.sh

 * Renamed option from '--literal-value' to '--fixed-value'

 * Use 'unsigned flags' instead of 'int flags'. This changes more prototypes
   than before.

 * Move flag definitions closer to method declarations.

 * Test the uses of --fixed-value to reject when value_regex is missing.

Thanks, -Stolee

Derrick Stolee (7):
  t1300: test "set all" mode with value_regex
  t1300: add test for --replace-all with value_regex
  config: convert multi_replace to flags
  config: add --fixed-value option, un-implemented
  config: plumb --fixed-value into config API
  config: implement --fixed-value with --get*
  maintenance: use 'git config --fixed-value'
