Subject: userdiff: add builtin driver for INI files
X-Git-Tag: v2.50.0-rc0~122^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=43380056df44aed6e074689dc8bc940f9dc6e2c8;p=thirdparty%2Fgit.git

userdiff: add builtin driver for INI files

Add a new builtin driver for generic INI files (e. g. the gitconfig
files), where:

- the funcname regular expression matches section names, i. e. any
  string between brackets at the beginning of the line, with or without
  indentation;

- word_regex matches any word with one or more non-whitespace
  characters without checking if it is a valid variable name or value.

Also add tests for the new userdiff driver. These files define sections
and subsections, with and without indentation.
