SCM Input - Display current line length for source control commit message input

HI! I care a lot for 50/72 commit message rule and I depend a lot on VSCode's source control's commit message input. The problem is that I always start to write, and I wait for the warning to appear, then if I'm in title, (first line), I try to change what I intended to say to contain only 50 chars; and if I'm in description (lines after the break after the first line) I write as much as I get the warning, and then I go back to before the current word and insert a new line there (press enter). This pattern is becoming so annoying. I want to observe how much I'm writing on the current line. A screen shot of what I have in mind:
