[PATCH 0/3] a few config integer parsing fixes

["Phillip Wood via GitGitGadget" <gitgitgadget@gmail.com>]

This series fixes some issues I noticed when reading the integer parsing
code in config.c

 * git_parse_unsigned() does not reject negative values
 * git_parse_[un]signed() accept a units specifier without any digits
 * git_parse_signed() has in integer overflow when parsing MAXINT_MIN

Ideally we'd have a test tool to unit test functions like this, I haven't
found time to write that yet. cc'ing René for patch 3 as he was the last
person to touch that code.

Phillip Wood (3):
  git_parse_unsigned: reject negative values
  config: require at least one digit when parsing numbers
  git_parse_signed(): avoid integer overflow
