Re: [PATCH 00/18] use semicolons rather than commas to separate statements

[Joe Perches <joe@perches.com>]

(Adding tools and Konstantin Ryabitsev)

There seems to be some mismatch between b4's use of the
cover letter to a patch series and what maintainers that
apply a subset of the patches in the patch series.

The merge description shows the entire patch series as
applied, but the actual merge is only a subset of the
series.

Can this be improved in b4?

For example, regarding:

I'm not so sure about that.

The commit merge description in -next shows 23 files
modified but the commit range shown in the merge shows
only a single patch applied:

From next-20201002:

    Merge series "use semicolons rather than commas to separate statements" from Julia Lawall <Julia.Lawall@inria.fr>:
    
    These patches replace commas by semicolons.  This was done using the
    Coccinelle semantic patch (http://coccinelle.lip6.fr/) shown below.

    regmap: debugfs: use semicolons rather than commas to separate statements
    
    Replace commas with semicolons.  What is done is essentially described by
    the following Coccinelle semantic patch (http://coccinelle.lip6.fr/):
