It seems to me that this will result in some changes, because the source
cache may hold text that has had styling applied, and so may have
embedded ANSI escape sequences -- which the search command isn't
expecting.

If this is needed for your source-embedding work then perhaps the source
cache should store an unmodified copy of the source as well, at least in
the case that styles have been applied.
