Before, inserting a newline did not move the prev_space index forward.
This meant that the next word was measured incorrectly since the
length was measured back to the word before the newly inserted
linebreak.
Fixes#828.
Before, wrapping the help text at, say, 80 characters really meant
that every line could be at most 79 characters wide.
Lines can now be up to and including avail_chars columns wide.
If needed, a desired margin or padding can be subtracted from the
avail_chars argument at a later point.
* tests: remove unnecessary mut
When building the projec, I was told
warning: variable does not need to be mutable, #[warn(unused_mut)]
on by default
--> tests/macros.rs:39:9

39 | let mut app = clap_app!(("app name with spaces-and-hyphens") =>
| ^^^^^^^
* examples: remove unused variable
The inner Some value is not used in the match arm:
warning: unused variable: `local_matches`,
#[warn(unused_variables)] on by default
--> examples/20_subcommands.rs:128:32
|
128 | ("local", Some(local_matches)) =>{
| ^^^^^^^^^^^^^
With these options, in case the completion function cannot provide
suggestions, Bash will perform its default completions, based on e.g.
files, directories, and variable names. This is particularly useful for
argument values.
Flags, Opts, and Positionals now store their internals using compartmented Base, Valued, and
Switched structs to keep the code duplication down and make it easier to maintain.
Iniside the src/app/parser.rs there have been several changes to make reasoning about the code
easier. Primarily moving related sections out of the large get_matches_with into their own
functions.
Try and stress the combinations of DeriveDisplayOrder and UnifiedHelpMessage
along with propagating them to subcommands and explicitly setting a display
order.
The new tests
derive_order_subcommand_propagate
unified_help_and_derive_order_subcommand_propagate
unified_help_and_derive_order_subcommand_propagate_with_explicit_display_order
are currently failing because of bug #706.
The new version of rustc 1.14.0-nightly (144af3e97 2016-10-02) has new
linting warnings/errors. This commit fixes them.

Added same alias funtionality for flags, now you can do:
```
Arg::with_name("flg")
.long("flag")
.short("f")
.alias("not_visible_flag")
.visible_alias("awesome_v_flag")
```

There are some cases where you need to have an argument to have an
alias, an example could be when you depricate one option in favor of
another one.
Now you are going to be able to alias arguments as follows:
```
Arg::with_name("opt")
.long("opt")
.short("o")
.takes_value(true)
.alias("invisible")
.visible_alias("visible")
```
Closes#669
* feat: adds App::with_defaults to automatically use crate_authors! and crate_version! macros
One can now use
```rust
let a = App::with_defaults("My Program");
// same as
let a2 = App::new("My Program")
.version(crate_version!())
.author(crate_authors!());
```
Closes#600
* imp(YAML Errors): vastly improves error messages when using YAML
When errors are made while developing, the panic error messages have
been improved instead of relying on the default panic message which is
extremely unhelpful.
Closes#574
* imp(Completions): uses standard conventions for bash completion files, namely '{bin}.bash-completion'
Closes#567
* imp(Help): automatically moves help text to the next line and wraps when term width is determined to be too small, or help text is too long
Now `clap` will check if it should automatically place long help
messages on the next line after the flag/option. This is determined by
checking to see if the space taken by flag/option plus spaces and values
doesn't leave enough room for the entirety of the help message, with the
single exception of of if the flag/option/spaces/values is less than 25%
of the width.
Closes#597
* tests: updates help tests to new forced new line rules
* fix(Groups): fixes some usage strings that contain both args in groups and ones that conflict with each other
Args that conflict *and* are in a group will now only display in the
group and not in the usage string itself.
Closes#616
* chore: updates dep graph
Closes#633
* chore: clippy run
* style: changes debug header to match other Rust projects
* chore: increase version
* test: `require_unless_one` with second argument
Add the `require_unless_one_2` test. This tests that when the second
argument in the array is used at the command line, that the required
argument is not present. This test was added because it appears the
`require_unless_one` function only works for the first argument in the
array.
* Fix: assertions for test
The assertions did not check for the `infile` to be present.
