runtime(vim): Update base-syntax, improve :let-heredoc highlighting Commit: https://github.com/vim/vim/commit/d164f2a521f8e52e587727657fb1c19e9a25f32a Author: Doug Kearns <dougkearns@gmail.com> Date: Fri Aug 16 21:07:15 2024 +0200 runtime(vim): Update base-syntax, improve :let-heredoc highlighting The end marker must appear on line of its own without any trailing whitespace. Whitespace is incorrectly allowed before all end markers. Limiting this only to heredocs where "trim" was specified, and with the correct indent, is currently an intractable problem given that contained syntax groups (in this case :let) cannot be limited to start patterns. Highlight interpolated expressions when "eval" is specified. cloess: #15511 Signed-off-by: Doug Kearns <dougkearns@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
