At the moment, only "syntax=asciidoc" was specified. The
asciidoc_filetype.vim that is distributed with Asciidoc gives the
installer two options -- to either associate every *.txt file with
asciidoc or to try to decipher whether or not the file is an asciidoc
using the first 50 lines.
So it's not given that a developer will open the *.txt files with
ft=asciidoc, and so it's helpful to have it explicitly in the modeline.
Again, by Chicago Manual of Style (CMOS) and several other style guides, we
hyphenate compound /modifiers/ when they come /before/ the word being
modified.
So the "command line" is not hyphenated, but the "command-line mode" is.
This is consistent with Vim help style conventions as well.
Most of the special case asciidoc replacements were also removed since
they're a bit confusing and doing so results in a 60% improvement in the
time taken by asciidoc to process the help pages. Unfortunately, I'm
now limited to preparing a three course menu for my guests while it runs
rather than the degustation extravaganzas of the past but such is life.
It's still a bit of a mess but since we're almost certainly moving to
something else in the near future it's probably not worth cleaning it up
before 2.0 is released.
