patch 8.1.0632: using sign group names is inefficient commit https://github.com/vim/vim/commit/7a2d9892b7158edf8dc48e9bcaaae70a40787b37 Author: Bram Moolenaar <Bram@vim.org> Date: Mon Dec 24 20:23:49 2018 +0100 patch 8.1.0632: using sign group names is inefficient Problem: Using sign group names is inefficient. Solution: Store group names in a hash table and use a reference to them. Also remove unnecessary use of ":exe" from the tests. (Yegappan Lakshmanan, closes #3715)

" This test is in a separate file, because it usually causes reports for memory
" leaks under valgrind.  That is because when fork/exec fails memory is not
" freed.  Since the process exists right away it's not a real leak.
