Improved limit-to-all detection by skipping leading spaces of the pattern.

There are many equivalent limit-to-all patterns, but in practice, one
may want to limit to " ~A" in order to prevent the pattern from being
recorded in the history. Thus it is important to detect at least this
pattern and similar ones.
