Re: [PATCH v4 00/12] ref-filter: use parsing functions

> This series cleans up populate_value() in ref-filter, by moving out
> the parsing part of atoms to separate parsing functions. This ensures
> that parsing is only done once and also improves the modularity of the
> code.

> Changes:
> * The parsing functions now take the arguments of the atom as
> function parameteres, instead of parsing it inside the fucntion.
> * Rebased on top of pu:jk/list-tag-2.7-regression
> * In strbuf use a copylen variable rather than using multiplication
> to perform a logical operation.
> * Code movement for easier review and general improvement.
> * Use COLOR_MAXLEN as the maximum size for the color variable.
> * Small code changes.
> * Documentation changes.
> * Fixed incorrect style of test (t6302).
