patch 8.0.1674: libvterm can't handle an OSC string split commit https://github.com/vim/vim/commit/77557a7ae66830cb21c79d3a2b48a93b086599b3 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Apr 7 21:42:56 2018 +0200 patch 8.0.1674: libvterm can't handle an OSC string split Problem: Libvterm can't handle a long OSC string that is split. Solution: When an incomplete OSC string is received copy it to the parser buffer. Increase the size of the parser buffer to be able to handle longer strings.
