42ddab0cb4 make missing_var a singleton 
Make the `env_var_t::missing_var()` object a singleton rather than a
dynamically constructed object. This requires some discipline in its use
since C++ doesn't directly support immutable objects. But it is slightly
more efficient and helps identify code that incorrectly mutates `env_var_t`
objects that should not be modified.

58b604c5ba change order of env_set() args 
It's bugged me forever that the scope is the second arg to `env_get()`
but not `env_set()`. And since I'll be introducing some helper functions
that wrap `env_set()` now is a good time to change the order of its
arguments.

fa4cf77aff Ignore more invalid arguments from parsed man pages 
Specifically closes #4313.
Not being as agressive in what we ignore/blacklist, but can be revisited
easily in the future to add more characters to the argument blacklist.

7b92217273 docs: improve set -Ux language and example 
By far the most common problem with universal variables being overridden
by global variables is other values being imported from the environment;
the `set -q; or set -gx` is much more of an edge case.

82b5ba1af4 fix bug in env_get() involving empty vars 
My previous change to eliminate `class var_entry_t` caused me to notice
that `env_get()` turned a set but empty var into a missing var. Which
is wrong. Fixing that brought to light several other pieces of code that
were wrong as a consequence of the aforementioned bug.

Another step to fixing issue #4200.

728a4634a1 replace var_entry_t with env_var_t 
This is a step to storing fish vars as actual vectors rather than flat
strings.

745a88f2f6 Revert "Fix clearing abandoned line with VTE (#4243)" 
Unfortunately, this breaks the expect tests.

So, until I can figure out how to unbreak them:

cf00162340 Fix clearing abandoned line with VTE (#4243) 
* Fix clearing abandoned line with VTE

With VTE-based terminals, resizing currently causes multi-line prompts
to go weird.

This changes the sequence we use to clear the line to one suggested by
a VTE
developer (https://bugzilla.gnome.org/show_bug.cgi?id=763390#c4).

It changes nothing in konsole 17.04.3 and urxvt 9.22, but they already
work.

Note that this does not fix the case where output did not end in a
newline, but that doesn't seem to be up to us. Also, it only affects
those lines.

Fixes #2320.

* Use terminfo definition instead of hardcoding

Thanks to @ixjlyons.
