Operator for toggling trailing symbols

This plugin defines two operator that toggles the existence of a particular symbol at the end of a motion or textobj. The implementation provides bindings for comma and semicolon, but one can easily add their own.

Requirements

This plugin depends on vim-operator-user.

Example settings

Put these in your .vimrc:

map <silent> ; <Plug>(operator-end-toggle-semicolon)
map <silent> , <Plug>(operator-end-toggle-comma)

Defining more operators

You can define new operators that toggle some particular symbol with the following code:

call operator#user#define('end-toggle-sharp', 'operator#end#toggle', 'call operator#end#set_symbol("#")')

Rationale

Consider the following C code:

int f() {
    int x = 42
    return x;
}

The code won't compile since we missed a semicolon at the end of the second line. We can easily append a semicolon by A, however how about:

int f() {
    int a = 1
    int b = 3
    int c = 6
    return a + b + c
}

This is likely to happen if you stay up late and somehow believe that you are writing in a language that doesn't require a semicolon to mark the end of a statement. If you want to repeat appending semicolon on each line, you might need to use macro or something more fancy. But with this plugin, you can simply do ;i{, and you are free to move on.

Miscs

This is my first Vim plugin, so the implementation might seems a little bit ugly. Any helps, found issues and PRs are appreciated.
