The old algorithm for detecting the first sentence of a JavaDoc comment
looked for the first occurence of '.'. This does not work when code or a
{@link android.R.styleable} link is encountered in the first sentence.
Switch to checking for whitespace characters after the '.' character.
Bug: 62900335
