25dd22242d Adjust __fish_print_help for sphinx 
This is beyond cheesy, but it seems to work.

Fixes #5782.

827bce6c88 Use mandoc when nroff not available 
mandoc users do not need to install nroff to be able to format and view
manual pages. If both nroff and mandoc cannot be found it will show an
error.

d727e32934 __fish_print_help: Just use $COLUMNS 
This had an undocumented internal feature that would pass the tty
width along. Instead, just have it read $COLUMNS, which we always
define anyway.

This removes the use of caret redirections from share/completions
and share/functions, in preparation for dropping support in fish.

a5fd0b317e Revert "Switch to bare vars in our math invocations" 
This reverts commit bd18736ee5.

Bare variables should only be used in commands that must
manipulate the variable stack, such as `set`.

bd18736ee5 Switch to bare vars in our math invocations 
Using bare vars is more efficient because it makes the builtin `math`
expression cache more useful. That's because if you prefix each var with
a dollar-sign then the fish parser expands it before `math` is run.
Something like `math x + 1` can be cached since the expression is the
same each time it is run. But if you do `math $x + 1` and x==1 then you're
effectively executing `math 1 + 1`. And if x==2 the next time then you're
running `math 2 + 1`. Which makes the expression cache much less effective.

8e87d595b7 remove some uses of $IFS 
This is a step towards resolving issue #4156. It replaces uses of `$IFS`
with other solutions.

9bc1b44b0d Handle missing groff macro in __fish_print_help 
The Xcode installation of Fish is missing the groff macro used by
`__fish_print_help`. This caused e.g. `status -h` to stop working.

Fixes #4058.

54a76bb9e5 emit error message when test is given invalid int 
This augments the previous change for issue #3346 by adding an error
message when an invalid integer is seen. This change is likely to be
controversial so I'm not going to squash it into the previous change.

222a07e907 Allow compressed man pages in help 
It seems Fedora compresses our whopping 340k of man pages.

Fixes #3130.

Inspired by @TieDyedDevil's work there.

cad1dc5293 Fix #1978:"ul: unknown escape sequence" when asking for help 
It seems that `ul` can't handle the escape sequences for bold text that `nroff` generates on my system.  Fixed by either removing `| ul`, or adding `-c` to the `nroff` command.

Needs testing for old (OSX?) versions of nroff.

76c6985f82 A little extra tweaking so builtin_print_help looks better 
The terminal width magic that __fish_print_help learned doesn't help
when builtin_print_help runs it in a subshell. Instead, add an
undocumented --tty-width flag to __fish_print_help that's used to pass
the terminal width.

ac8c5910eb Rewrite __fish_print_help to produce better results 
As a result of this rewrite, the output now:

* Expands to fit the terminal width, like `man` does
* Preprocesses the manpage with `tbl` just in case, since `man` does
  this, even though I doubt any fish manpages use `tbl` formatting.
* Handle bold/underline with the `ul` command as it was designed for
  instead of trying to fake it with `sed`.
* Compresses blank lines as `man` does with the default `less -is`
  pager.
