Sounds reasonable. I'll amend the commit, and send a new patch set in a few moments.

Also, I'd like to note that other sections of the Expansion chapter such as "14.3.1 Parameter Expansion Flags" need some template decorations too. I mean, try to search the page for, let's say, a letter "t". Unless you are a *NIX shell guru and know exactly where and what to look for, you are toast. Readability and discoverability of this documentation can/should be improved by a lot.
