pattern match characters support ^Q/^R now as well
* makes it possible, albeit cumbersome, to escape pattern match characters
* For instance, to search for ^Q, you now have to type
S^Q^Q^Q^Q$.
To search for ^E you have to type
S^Q^Q^Q^E$.
But the last character cannot be typed with carets currently (FIXME?).
For pattern-only characters, two ^Q should be sufficient as in
S^Q^Q^X$.
* Perhaps it would be more elegant to abolish the difference between string building
and pattern matching characters to avoid double quoting.
But then all string building constructs like ^EQq should operate at the pattern level
as well (ie. match the contents of register q verbatim instead of being interpreted as a pattern).
TECOC and TECO-64 don't do that either.
If we leave everything as it is, at least a new string building construct should be added for
auto-quoting patterns (analoguous to ^EN and ^E@).
