[FFmpeg-devel] [PATCH] libavformat/matroskaenc: reformat options table indentation and descriptions

[Marth64 <marth64@proxyid.net>]

matroskaenc options table has grown packed over time, and is now challenging
to read. The purpose of this patch is to reformat the table, indentation-wise,
and to make the capitalization/endings of each description at least consistent.

I intend to sort the options in a follow-up patch, but wanted to phase
this out to be easier to validate.
