I proposed this edit to a Stack Exchange answer. Because there were three rather lengthy block quotes, I thought bolding the most relevant sentences would be helpful to readers, especially if they were skimming the page.
This is the latter part of one such quote, and the note I added following it:
For the shell's purposes, a command which exits with a zero exit status has succeeded. An exit status of zero indicates success. A non-zero exit status indicates failure. When a command terminates on a fatal signal N, bash uses the value of 128+N as the exit status.
(The outer quote is an excerpt of the mentioned answer; the answer quotes the manual page of the Bourne Again Shell.)
The bolding mine note was meant to claim the addition of boldface—but not of italics!—in both that quote and a later quote in the answer. Italics were present in the quoted manual page. (Actually, I, an editor, bolded the text, but I don't feel that's relevant here.)
Is this clear enough, or should I do something else?
