@Adakiko: Here are two CSS rules:

/* For current rev in contribs, add "(C)" before the size change */
li.mw-contributions-current span.mw-changeslist-links+span.mw-changeslist-separator:after {
  content: "(C)";
  font-weight: bold;
}
/* For current rev in contribs, suppress the "(current)" marker */
li.mw-contributions-current span.mw-uctop {
  display: none;
}

The second rule is optional. They go in Special:MyPage/common.css, since it works in all skins. But personally I use a rule that I wrote some months ago:

/* highlight current edit in contribs */
li.mw-contributions-current {
  background-color: #eeffcc;
}
