8b858f2fcc Use a custom Lynx style sheet (LSS file) to work around Lynx bug 
Lynx uses a very naïve method of applying styles to HTML elements by
hashing the element type and the class name to generate a map of
hash:style. After the hash is calculated, Lynx does not go back and
check whether or not the actual string values match the LSS properties.

See the following links on the Links mailing list:
 * http://lists.gnu.org/archive/html/lynx-dev/2015-12/msg00037.html
 * http://lists.gnu.org/archive/html/lynx-dev/2015-12/msg00039.html

This patch copies the default Lynx stylesheet but removes highlighting
and other styles that would result in unreadable text (due to not enough
contrast with the background color), and if the `help` builtin detects
that the best web browser to use is Lynx, it instructs it to use this
modified stylesheet.

2b425ad221 Don't use xdg-open if running in terminal mode (i.e. no Xorg) 
If the $DISPLAY environment variable is not set, xdg-open should not be
used to load the web browser. Just because it is installed does not mean
that the user exclusively runs in an X session.

Needed for Lynx detection to work around #4170

11a60c8374 reformat all fish scripts 
I hate doing this but I am tired of touching a fish script as part of
some change and having `make style` radically change it. Which makes
editing fish scripts more painful than it needs to be. It is time to do
a wholesale reformatting of these scripts to conform to the documented
style as implemented by the `fish_indent` program.

89206d8654 Fix user browser for help in Cygwin 
Fixes the invocation of a user-specified browser by the `help` command on Cygwin.

- Use `cygstart` to launch the browser with escaped quotes to avoid problems with spaces in the path to the browser, (e.g. Program Files).
- Use `cygpath` to convert the base help dir to a Windows path before constructing the fie URL to pass to the browser.

5fca92994f help.fish: Fix the sed expression to find anchors with id or name 
Previously the expression only searched for anchors with a name
attribute, but doxygen 1.7.1 is producing anchors with the id attribute
instead. The sed expression allows both cases for compatibility.

I also used single quotes for the sed expression to avoid escaping
double quotes.
