aports/community/ast-grep/remove-some-parsers.patch

From: Jakub Jirutka <jakub@jirutka.cz>

Subject: Remove some big parsers

Remove parsers for less used languages (on Linux) that contribute most
to the size of the resulting binary. This cuts the size by half - from
~41 MiB to ~20 MiB.

ast-grep provides some support for dynamically loaded parsers, but it's
still experimental and it would require a non-trivial work to use it
for loading "built-in" parsers.
