[Yann E. MORIN]

Bernd, All,

On 2020-02-01 13:59 +0100, Bernd Kuhls spake thusly:

This line was too long, causing check-package to complain:

    package/libiconv/Config.in:17: help text: <tab><2 spaces><62 chars>
    (http://nightly.buildroot.org/#writing-rules-config-in)

So I removed two of the indenting spaces, and we're good.

Applied to master, thanks.

Yann E. MORIN.
