New punctuation text objects

ci/, di;, yi*, vi@ ...
ca/, da;, ya*, va@ ...

---

ciq (or "") changes content inside ANY kind of quotes
vaq, yiq ...

---

ci<space>, da<space> ... modify ANY punctuation pair

Supported punctuation signs

` " '
! $ % ^ & * _ - + = : ; @ ~ # | \ , . ? /

Algorithm:

Do in order. If a step succeeds skip the rest.

1. same line: match under the cursor: act to the right if possible, else to the left
2. same line: jump to a match on the left, then act to the right if possible or else repeat
3. same line and ↓: try matching to the right, also past the current line if no match till EOF, start from byte one and do the same till initial position of cursor

Examples:

[] and | will represent the cursor

ciq or ""

Lorem [] dolor "          " adipisicing elit
Lorem    dolor "|" adipisicing elit

---

da^ or da<space>

Lorem    dolor "    ^ []  ^     " adipisicing elit
Lorem    dolor "         " adipisicing elit

---

vi@ or vi<space>

Lorem    dolor @        @        [@]  adipisicing elit
Lorem    dolor @        @---------@   adipisicing elit

Note: the above is different from what Vim would do.
explanation: '      '      ['] then ci' WON'T change anything!

---

di; or di<space>

Lorem  %     %  []  ;            ; elit
Lorem  %     %      ;; elit

---

gUiq

Lorem    dolor  '    val `  X  ' orem       ` adipisicing elit
Lorem    dolor  '    val `  X  ' OREM       ` adipisicing elit

---

yi. or yi<space>

Lorem    dolor  sit amet  []   adipisicing elit
incididunt ut labore .dolore. aliqua

Now: dolore is in reg "

---

""

START OF FILE
Lorem    dolor  ' sit amet     '  adipisicing elit
incididunt ut labore et dolore [] magna aliqua.
EOF

Result after searching for a match and wrapping around EOF:

START OF FILE
Lorem    dolor  '|'  adipisicing elit
incididunt ut labore et dolore [] magna aliqua.
EOF
