eliminate junk from std.string?

[Ary Borenszweig]

Oh, one more thing: can the names be consistent?

inpattern
countChars
expandtabs
chompPrefix
toupper
toupperInPlace ??

If this can't be done for backwards compatibility maybe you can make alias for the
previous ones.

Also:

stripl
stripr
strip

Strips *l*eading and *t*railing whitespaces...

It took me some time to notice that it was strip*r* (for right), but the comment
says "trailing", and I never think of "remove right space", always "remove
trailing spaces" (like in the comment!). So why not name that function "stript"?
