8df9a4d271 Fixes potential segmentation fault in edge cases. (#465) 
The options are parsed starting from 1, so check `current < argc`
instead of `!=` in the case that `argc` is zero.

80cb4520f7 Fix some warnings (#452) 
* Move `result` up and return it

This allows `gcc` to elide the copy in the return and keeps it from
warning with `-Wnvro` enabled.

* Remove harmful dtor definition

The definition of the dtor is not necessary and actually harmful since
the definition of a class's implicit copy constructor is deprecated if
that class has a user-declared constructor as of C++11.  Compilers can
warn about this with `-Wdeprecated`.

e84ab5f67c Fix overflow error in integer_parser. (#417) 
Fixes #290.
Checking for overflow should be done before integer overflows.
There are two checks:
(result > limit / base) is used for limits greater than rounded up to base,
e.g. for 65535 it will activate for 65540 and higher.
(result * base > limit - digit) is used for limit+1 to limit+n below
next base rounded number, e.g. 65536 up to 65539.

e976f964c3 Fix issue #240: Multiple long option names / aliases (#349) 
* Fixes #240: Multiple long option names / aliases

* We now use a vector of long option names instead of a single name
* When specifying an option, you can provide multiple names separated by commas, at most one of which may have a length of 1 (not necessarily the first specified name). The length-1 name is the single-hyphen switch (the "short name").
* Hashing uses the first long name
* Option help currently only uses the first long name.
