Doesn't seem to be a way to use '\' in subst with back_references





------- Additional Comments From vgritsenko@apache.org  2004-05-27 12:03 -------
I think that patch introduces more confusion than it solves. \$ without
REPLACE_WITH_ESCAPES is still escaped - but logic suggests otherwise.
Additionally, behavior of escaping $ with \ is not documented in Javadoc and not
reflected in the unit test.

Because this behavior is not documented, and it was introduced recently (in
previous release), I suggest to change it (and document in javadoc / unit test).
I suggest following syntax:

When REPLACE_BACKREFERENCES is on:
  Process all $ as backreferences. No escaping performed at all.

When REPLACE_BACKREFERENCES and REPLACE_WITH_ESCAPES both are on:
  Process all $ as backreferences.
  Process \ as escape symbol.

So, what do you think?
