Trailing slashes not stripped from cache path

The source says:

^edded64 source/acfg.cc (Eduard Bloch   2014-05-03 21:22:17 +0200  752)    // get rid of duplicated and trailing slash(es)
^edded64 source/acfg.cc (Eduard Bloch   2014-05-03 21:22:17 +0200  753)         for(tStrPos pos; stmiss != (pos = cachedir.find(SZPATHSEP SZPATHSEP )); )
^edded64 source/acfg.cc (Eduard Bloch   2014-05-03 21:22:17 +0200  754)                 cachedir.erase(pos, 1);

^edded64 source/acfg.cc (Eduard Bloch   2014-05-03 21:22:17 +0200  756)         cacheDirSlash=cachedir+CPATHSEP;

But in fact, that only strips double slashes, not trailing slashes.
