top: modify 'Ctrl' bottom window 'str' use with 'strv' <=== port of newlib 73b4f113
______________________________ original newlib message After satisfying increased buffer size in the previous patch, I decided to improve the highlight accuracy for both the command lines plus the environment variables. Since they both may contain elements which themselves include embedded spaces, to accomplish this goal, one must trade vanilla strings for string vectors instead. [ at last such library items have now been justified ] Signed-off-by: Jim Warner <james.warner@comcast.net>
