patch 9.0.2040: trim(): hard to use default mask Commit: https://github.com/vim/vim/commit/6e6386716f9494ae86027c6d34f657fd03dfec42 Author: Illia Bobyr <illia.bobyr@gmail.com> Date: Tue Oct 17 11:09:45 2023 +0200 patch 9.0.2040: trim(): hard to use default mask Problem: trim(): hard to use default mask Solution: Use default 'mask' when it is v:none The default 'mask' value is pretty complex, as it includes many characters. Yet, if one needs to specify the trimming direction, the third argument, 'trim()' currently requires the 'mask' value to be provided explicitly. 'v:none' is already used to mean "use the default argument value" in user defined functions. See |none-function_argument| in help. closes: #13363 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Illia Bobyr <illia.bobyr@gmail.com>
